15-Minute Cycling HIIT Beginner

A Tabata workout on the bike: four 4-minute Tabata blocks (8 rounds of 20 seconds all-out sprint and 10 seconds rest) with 1 minute of recovery spinning between blocks. The bike is actually one of the best tools for Tabata because you can push to true maximum effort without the injury risk of ground-based sprinting. The 20-second sprints should be absolute maximum power output — your legs should be screaming by round 6. Twenty minutes total including warm-up and cool-down. Intermediate difficulty — the Tabata protocol is inherently brutal but the bike makes it more accessible than other modalities.

FTP (Functional Threshold Power) builder workout: 3 rounds of 8-minute sustained efforts at your threshold with 4-minute easy recovery between each. Your threshold is the highest intensity you can sustain for roughly an hour — working at this intensity for shorter intervals is the most effective way to raise it. A 10-minute progressive warm-up prepares your legs and cardiovascular system for the demanding efforts. Forty-five minutes total including a 5-minute cool-down. Advanced difficulty — you should know your approximate FTP or threshold heart rate to pace these efforts correctly. This is the workout that makes you a stronger cyclist.

A pyramid interval structure on the bike: work periods build from 1 minute up to 4 minutes at the peak, then descend back down. The ascending phase progressively challenges your ability to sustain hard efforts for longer periods. The descending phase rewards you with shorter efforts as fatigue accumulates. Rest periods are proportional — more rest after longer efforts. The pyramid format is one of the most mentally engaging interval structures because the changing durations prevent monotony. Thirty minutes total including warm-up and cool-down. Intermediate difficulty with self-selected intensity for each interval.
