Week #2 of my Performance Cycle class and I introduced the concept of using your stage average watts as a “riding buddy” today + had a nice email when I got home.
Hi John-
Thank you so much for the great class this morning. I took a picture of my results when I was finished. My avg watts was 148, not 212. I have no clue where I got that number. 😉
I also took your advice and upgraded my membership, so if it's ok with you, I would like to take advantage of the class next Sunday as well. Do I need to come early to be tested or will this take place during your class?
My goal is to get strong and gain endurance. I have an Ironman in 2014 that I would love to CRUSH! 😉
Thanks again for the great morning!!

This gal is an animal – the 212 watts she refers to was her average for both of the 10 climbs we did, with only a minute of recovery in between them. Here's the picture she took.
Those are awesome #s for anyone.
Now to the Riding Buddy
Pictured on the right is a Garmin 810 cycling computer. Beyond measuring and displaying all the typical stuff; RPM, MPH, Distance, Time elapse, etc… these computers allow you to race against a Virtual Partner, which is yourself previously riding over a known course. Racing against yourself is afascinating concept which allows you to compare today vs last week or last year. Are you getting stronger/faster/fitter? Yes? No?

After all, it's just you, who you're really racing against.
I use the stage average timer in class as a sort of Riding Buddy, comparing a specific intervals against earlier efforts. Asking; are you keeping up? Yes? No?
Warm Up — 10 minutes. 5 minutes of gradual increases in wattage. During the second 5 mins. we’re finding the wattage where everyone is first noticing a change in breathing; VT1 / Aerobic Threshold = the top of the Recover Zone shown above. This establishes a rough understanding of a base wattage that we use throughout the rest of class.
3 x 30 sec. Hard / 30 sec. Easy – Openers to AT/LT. I cue these by first having everyone find the amount of load @ 70 RPM that has them feeling they should (not just could) come out of the saddle. The 30 sec. Hard is then simply accelerating to 90+ RPM which results in some pretty impressive power numbers. The 30 sec. Easy is back to 70 RPM — many will stand during the Easy portion.
3 minutes rest – I encourage riders to focus on their recovery. Once they feel calm in their breathing, bring back the Base level work wattage.
5 min. Short Hill — Here's were we do our 5 min. “Best Effort” to establish a benchmark PTP Personal Threshold Power (top of the Perform Zone) or ride at 110% of FTP if known. It’s very helpful to riders to have that understanding of their personal upper wattage number. The “Best Effort” Threshold # + the Base Threshold # we found earlier form the three Power working zones I use in class.
– 1 min. build at preferred cadence (suggested as 85-95 rpm) — press the Stage Button to reset the averages.
– 5 min. “Best Effort” This should hurt, but be do-able. I ask everyone to observe their average at the end and then…
2 minutes rest
3 x 5 min. Medium Hill @ 1 min Rest – Now that everyone knows how hard they can go for 5 minutes, we worked at ~90% of PTP on each of the three, five minute climbs. The recoveries and transitions back to climbing are simplified by leaving resistance where it is and do what I call Walking. Have everyone stand and pedal slowly “walk” for a minute. Load should be too high for seated soft-pedaling. Then accelerating up to preferred cadence brings everyone back to ~90% of PTP.
3 minutes rest
2 x 10 min. Long Hill @ 2.5 min. Rest – the songs I used were a little short so I had everyone up to RPM/Watts before starting the songs and hitting the Stage button to establish averages. I prefaced the first climb with; “As Endurance Athletes, you recognize that you get stronger as the class goes on.” Here's where I got a few smiles and hoots… “so my expectation is that you can all climb this at your PTP (5 min. Best Effort wattage)” and we did 🙂 The Spinervals profile calls for near constant changes in gears and cadence, which is easy to do on a bicycle… not so easy on an Indoor Cycle. So instead we made 3-4 changes in load/RPM + alternated in & out of the saddle.
Here's where I was cuing everyone to focus on their Riding Buddy. No matter the change, it is imperative that you keep your instantaneous watts at or above the average, so you keep up with your Riding Buddy.
5 minutes at Base wattage @ 90RPM – which becomes a recovery > step down in intensity while we stay aerobic.
Cool Down
I'm very excited to be able to teach these Performance Cycle classes – they fit me and my personality perfectly and we have an excellent group of athletes to ride with.
Next Sunday 1/5 is the official kickoff of the winter training program > FTP assessment day. Feel free to contact me if you'd like to ride with us.
I was reading this post over at Pedal-On this morning. In it an Instructor was asking about securing a teaching position with Life Time Fitness – where Amy and I have taught for years and feel we know the company well.
After posting my response a thought occurred to me; “teaching for a large multi-location chain like Life Time Fitness, with thousands of members and huge studios has it's own unique challenges… and I don't know that our existing resources really address the needs of a Big Box Instructor.”
So as a new service for our ICI/PRO members we will begin offering resources that are designed specificily toward helping those of you who teach at a Life Time Fitness, LA Fitness, 24 Hour Fitness, Equinox or other large Big Box health club.
You will be able to find this new category under the Instructor Training > Big Box Instructor navigation drop downs above.
Here was my response to the question about Life Time Fitness:
I've taught for Life Time Fitness for 6 years. I have scheduled classes at two Athletic (Diamond) level clubs here in MPLS where it's all about the members. I also sub regularly at the Chanhassen club that shares the parking lot with the LTF corporate headquarters. For you or anyone else looking to join LTF as an Instructor I can offer this advice:
1) Memorize the LTF mission statement –
Our Mission is to provide an Educational, Entertaining, Friendly and Inviting, Functional and Innovative experience of uncompromising quality that meets the health and fitness needs of the entire family.
I'm not kidding when I say memorize it as you will be expected to deliver it as part of any interview or Instructor audition.
2) Contact the club's Group Fitness dept head and ask to schedule a time for a call or better to meet with them in person. Do not call and just ask if they are holding instructor auditions. Your objective is to meet the Dept Head to learn what she/he is looking for in the Instructors they hire… which may be very different than who is currently teaching classes at the club. If the club is looking for someone or has a scheduled audition time they will tell you. Also, my experience is that Dept Head's do have some authority to hire someone without holding any auditions if they like/need you.
3) LTF is very focused on their Club within a Club initiative where they create small groups of interest; Run Club, Cycle Club, Tri Club, Swim Club, etc… If you are an outdoor cyclist I suggest contacting Cycle Club coordinator at the location and become their friend LTF is very interested in Instructors who could potentially take their Indoor class participants outdoors.
4) Understand that first and foremost your role as an instructor is to deliver a fun and entertaining experience for the members. You may teach the most real/authentic cycling class on the planet, but if it's boring because you feel constrained by focusing too much on what not to do, it will show in your class presentation and your chances of getting hired are slim. LTF's head of Instructor training Jeff Rosga said it best; “first you need to give them what they want, and then give them what they need.”
5) If you do get an audition, teach a class that's appropriate to the audience. LTF wants to see that you are flexible as an Instructor and can teach appropriately to varying member groups. You may teach a very “cycling specific” class, but that isn't what a room full of housewives want during a 9:30am class. (See #4)
6) Once you do get hired you can typically teach the class you want, remembering #4, as long as your numbers are reasonable, without interference from management. You are expected to follow the periodization schedule as to the objective of the class – but that doesn't dictate the actual profile you use.
Now I know there are many of you who instinctively revolt at the whole “you need to internalize our Mission Statement” group think thing. I know I did at first.
But when you consider that Life Time has thousands of Instructors, who are in front of something like half a million members each month, you really do need to find ways to keep some consistency of instruction… without forcing Instructors into little boxes that crush all of their creativity and passion for fitness.
I can think of a bunch of people I could have on the Podcast to explore the challenges and issues facing the Big Box Instructor. Stay tuned…
First I have to apologize for taking almost 2 months to report on results that were secured after just 4 weeks of data collection. That’s part of the problem with Evidence Based Cycling; once you do herd all those cats on bikes (see last post) and send them on their way to collect data, you have to eventually herd them over again to retrieve the data. I only got the final piece of performance data last week.
I won’t hold you in suspense any longer, the results appear below in summary form — with the bottom line of: “What effect if any did this protocol or riding drill have?“ or perhaps more simply stated “Did we get an better?” or better yet, would it be more appropriately states as “can this protocol be used as a specific prescription for improving Muscular Endurance in cyclists?” Frankly, I want to know that for myself and my own riding, as much as I want to or need to know it for the riders I coach personally.
Summary Results
The summary results shown here simply compared the Baseline Test (our method for determining their power generation and sustainability levels at the start of the test) to their Performance Test that sought to measure the same thing, on the same bike, in the same manner. The results seem to suggest that this riding drill for improving Muscular Endurance works.
SUMMARY RESULTS
Muscular Improvement
Endurance Improvement
Efficiency Improvement
Average Change:
5.03%
3.35%
17.29%
Throwing out High & Low:
5.04%
5.04%
13.90%
The one fact that can, and often does bring seemingly good findings into question is the sample size. While we started with 11, we ended up with only 8 riders who completed the study. There are a variety of reasons for this, none of which had anything to do with the test itself. In any event, to be considered valid by almost any rigorous standard, this type of study would have to be repeated with a bigger sample size. May this preliminary “investigative type research” would inspire some budding graduate student in the physiological sciences to pursue a wider study.
Are The Results Statistically Significant?
In terms of whether we can consider these results meaningful or not, we must first introduce the term or phrase associated with this question; “statistical significance”. In regards to research findings, it has a fairly specific definition. Wikipedia explains it this way: “Statistical significance” is a statistical assessment of whether observations reflect a pattern rather than just chance…” It further defines the level or degree of significance this way: “The choice of significance level is somewhat arbitrary, but for many applications, a level of 5% is chosen by convention.[3][4]”
As you can see from the summary results, by all accounts calculated, only the Average Change in Endurance would come into question. This is quite understandable given the fact that these results were assessed only 4 weeks after the study began. In training other athletes, and in training myself as a semi-retired racer, I can tell you that most real and lasting training effects take 6 weeks to be “established”; established as in the gains are likely to not be reversed any time soon, and that there was a real cause and effect relationship between the work and the result.
The Gory Detail
Below is the table with all the numbers that make up the summary findings above. Data geeks control yourself — these numbers only represent 4 weeks of following the M.E. protocol, and we need much more data to begin to think of implications beyond the obvious conclusions drawn from what we see here. That will be the focus on our next blog post — what all can we see and say about this data and its implications for both training and further research.
This is the companion Audio PROfile for the Epic Planet DVD Epic Wine Country. You can use it as the basis for an exciting and entertaining class. It features a 20 minute endurance section where you can conduct a T1 Aerobic Threshold assessment and pre-fatigue everyone’s legs, during the flats, before heading into the hills. The 25 minute mark signals the start of 2 major climbs of 9:22 and 10:56 with very little recovery in between. The key to your student’s success on these long climbs is to balance the work between their cardiovascular and muscular systems. To do so, we want to encourage everyone to keep their cadence up above 70 RPM for the entire class.

Here's your Spotify PRO/Playlist!Deezer. We have made every attempt to replicate the original playlist. In some instances the tracks specified were unavailable in Spotify. When necessary we have substituted individual songs of similar length and tried to maintain the Instructor's intent.
Interval: n., the amount of time between two specified instants or events.
You teach indoor cycling, so you know intervals. If you asked another instructor for the workout he/she used in class that morning, odds are you’d get a response something like, “The main climbing set was 4 X 5/1:30 min at 85%,” indicating four five-minute climbs at 85% max effort, with 90 seconds of recovery between efforts.
Intervals are standard practice in indoor cycling and all types of CV training because of how effective they are. Interval training dates back to the 1930s, when German coach Dr. Woldemar Gerschler pioneered training methods based on sound physiological principles. He teamed up with cardiologist Dr. Herbert Reindel to develop a training protocol that would maximize the heart’s fitness.
The study involved some 3000 subjects completing three weeks of precise, heart rate-controlled training. The participants were track athletes who ran a relatively short distance at a very fast pace. Average stroke volume increased 20%, with significant improvements in performance. Gerschler and Reindel dubbed the repetitions “interval training” and considered the recovery period between the runs the most important part of the training.
When I first read this, I was amazed. To the founders of interval training, “interval” meant the recovery interval. When managed correctly, that period of time had the greatest physiological impact. The descriptive “formula” I used above would have made no sense to them because the rest interval should be the primary concern and dictate the repetition of the work effort.
For Gerschler and Reindel, if my heart rate did not recover properly in 90 seconds, I wouldn’t be allowed to do the next interval. Improved fitness would have occurred when my heart rate actually achieved the desired recovery in 90 seconds.
If that heart rate reduction didn’t occur, the workout was too difficult. Unless it was adjusted, the heart would be overworked, leading to fatigue and exhaustion, rather than to the desired training effect. So, the reduction of the recovery interval is the most important aspect of the training, not the degree of effort or duration of the work interval.
Consider the state of training within indoor cycling today in light of that information. Rigid interval formats form the core of most classes, with limited (or no) attention paid to what the founders of interval training actually meant by interval training. And not just in indoor cycling. Consider the prevalence of high intensity interval training (HIIT), such as the Tabata Protocol, in the fitness industry in general. Tabata intervals are often max efforts with extremely short recovery — less than half the duration of the work interval. Consider Gerschler and Reindel rolling over in their graves.
Is respect for recovery even possible with current class schedules, equipment or perceptions? My guess is no, except in selected, controlled situations. Is it even desired by the average class member? Most of them would not feel they were getting a good enough workout because we gave them too much recovery.
As indoor cycling instructors, we’ve all heard, “It’s not how hard you work but how fast you recover.” Yet it’s difficult to implement, given what we have to work with, and that includes the mindset of our members.
Maybe the question becomes whether or not we should really be doing intervals at all. When an interval is considered as described in the first sentence — the amount of time between two specified instants — then it’s a valuable tool for us as instructors. It allows us to develop patterns and give participants an understanding of the training we have planned for them. It also enables us to implement music more effectively by selecting songs by length to fit the patterns that we create.
As soon as “interval” becomes “interval training”, however, I think it’s wise to take a step back and consider where this kind of training came from and what the founders of interval training discovered about the work/recovery relationship.
Josh Taylor had told me last year about a new pedal Spinning® was designing that would have the same versatility as the Schwinn Triple Link pedal; accepts LOOK, SPD and fitness shoes + they include the new Morse Taper pedal spindle (vs. a conventional threaded spindle) they're using on the new Spinner® NXT and Blade Indoor Cycles.
I see now that they've introduced the new pedal in two versions; the TRIO™ and TRIO QR™ – QR refer's to Quick Release.
My understanding is that even with dozens of different competing pedal types available, LOOK (who was the first mass-marketed clip-less pedal) is still the market leader in road bike pedals. So it makes good sense to offer these types of pedals to keep many of your cyclists participants happy 🙂
The two pedals appear identical except for:
Patented “Quick Release” lever allows for simple one-handed platform removal.
They may want to reword this as the owner's manual clearly shows you need two hands to remove the cage.
One hand or two, my hat's off to whomever designed the nifty Quick Release feature on the TRIO QR!
Fun Fact
You may or may not be aware that indoorcycleinstructor.com, the Podcast, ICI/PRO… everything began with my desire to market my Red Pedal Tool. After years of fighting with the shoe baskets on these pedals I created this tool which is designed to safely and easily remove the shoe basket from Schwinn Triple Link pedals.
I'll need to talk with Josh about why they have also chosen to manufacture a version without the quick release… The diagram below illustrates the very same removal issue Schwinn has with their Triple Link.
LTF is very interested in Instructors who could potentially take their Indoor class participants outdoors.
