Long Duration Waves last 2-5 minutes per interval. W:R is typically 1:1.
Alternate lower body focused cardio machines (treadmill, stepmill, bike, etc) with upper body focused cardio machines (rower, ski erg, infinity rope, etc). Whole body cardio may be introduced as well (air bike, jump rope, elliptical, etc). Shadow boxing or heavy bag work counts as upper body, kicks as lower.
Each round takes 16 minutes. 1-4 rounds recommended.
