Sweet Spot Strength Intervals
Cycling, May 03, 2025
Sweet Spot is an intensity that is just below your Functional Threshold Power (FTP). At this intensity, you get the physiological benefits without the level of fatigue of higher-intensity sessions. This session is great for all cyclists including triathletes and mountain bikers.
See a previous post about training intensity (Levels) to know how hard it is to work. If you are working directly with Coach Ray he will in most cases prescribe either a Power Zone or Heart Rate Zone to work within if you are training with these tools.
This is an adaptation of a workout from Triathlete Magazine. You can read the full article here.

Start the workout with a fifteen-minute warm-up (WU) riding at Level I.
To build your Heart Rate and prepare your muscles for the intensity to follow next up is a set of five, 30-second intervals at Level III, and have a 30-second Rest Interval (RI) riding at Level II between reps.
The main set is made up of two reps, each with two parts.
Start the first rep with five minutes of riding at the bottom end of Level III (Level III-) the article describes this as 75-80% of your Functional Threshold Power (FTP). Ride at a low cadence of 60-65 rpm.
The second part of the first rep is lifting your effort to Level III+ for seven minutes, which is described in the article as 88-95% of your Functional Threshold Power (FTP). This Sweet Spot riding should be done at a higher cadence.
Ride for two minutes at Level II for your Rest Interval (RI).
The second rep starts with five minutes at Level III+ for seven minutes, which is described in the article as 88-95% of your Functional Threshold Power (FTP). This Sweet Spot riding should be done at a higher cadence.
Then finish the second rep with seven minutes of riding at the bottom end of Level III (Level III-) the article describes this as 75-80% of your Functional Threshold Power (FTP). Ride at a low cadence of 60-65 rpm.
Complete a Cool Down (CD) for ten minutes at Level I.
Finish with ten minutes stretching to assist with your recovery.
