Nice video. I do cycling, so workouts are a bit different than someone who would be lifting. I do 60+ min rides with HITT sessions in them. I do 5 all out sprints in the middle of a ride to the point where my legs are on fire and max heart rate peaks. Then I keep the cadence up above 90rpm to recover for a few min while I continue on my ride. Normally works out to 20 min medium pace, 15-20 HITT and 20+min after. I try to keep my heart rate outside of the HITT sessions in zone 4. Doing this type of workout and cutting calories I have lost 25lbs over the past few months with no loss of power. Diet is depending on the workout for the day. If LISS day then no morning carbs, if LISS and HITT day then 30-40grams of carbs in AM. Rest of day is low carb. I also do calisthenics and core throughout the day as breaks from work.
