What the What?
There are so many acronyms about fitness floating out there… let’s get to talking about a couple.
HIIT – high intensity interval training. Hmmm… Intensity, intervals… sounds a lot like a Corps Fitness class, doesn’t it? Think timed stations, Tabata, or even sets of reps with planned “rest” built in. The key is to maintain the INTENSITY and then take advantage of the rest (but being ready to push that intensity every time… did I mention that yet?). If you just go through the motions without pushing yourself to an uncomfortable intensity for the designated time, you’re not doing yourself any favors and won’t reap as many benefits.
LISS – low intensity steady state. Think “active recovery” – taking a walk a few times a week, riding a bike, etc. Keep your intensity at a 3-4 on a scale of 1 (low) to 10 (high).
CrossFit takes on a little of each, especially CF-style CrossFit where we’re active for an hour. Depending on the workout, you might be sustaining intensity a little longer than HIIT but not as low as the 3-4 intensity level to qualify as pure LISS.
The key is to keep your body guessing, not allowing it time to adjust to one mode or the other. Form follows functions, so challenge yourself and keep it interesting both for your mind and for your muscles!
