04 PICK A PROTOCOL
Got an aim and staked out a corner of the gym for yourself? Go for it
BEGINNER TIMMONS METHOD
Developed by a team at Loughborough University, this one’s entry level. Do 20 seconds of all-out work, followed by two minutes of active recovery (walking/freewheeling will do) or complete rest. Repeat three times, and you’re done.
INTERMEDIATE 10 20
Also known as “reverse Tabata”, this doubles the rest and reduces the work intervals to shift the focus to anaerobic fitness. Use it if you’re aiming for power production, or if you don’t have the fitness for an all-out Tabata. Warm up for ten minutes, then do six to eight rounds.
ADVANCED 10 20 30
Now things get complicated. In this plan, you’ll do five “blocks” of work, made up of 30 seconds at 30% intensity, 20 seconds at 60% and ten seconds all-out. Result? Lots of volume, at manageable intensity.
The most famous HIIT protocol is ideal for increasing V02 max – as long as you do it right. Twenty seconds of all-out work, followed by ten seconds of rest, repeated eight times, improved endurance as much as 30 minutes of steady-state cardio in a Queen’s University study. The key is keeping intensity high – if you can talk during the session, you’re getting it wrong.
