I've been in a sort of lean out phase - feel ridiculously good right now. Mostly HIIT w core and focus one day upper next day lower third day power movements. 4th day usually a ruck or just cardio and repeat.
Right now leaner than I have been since did shows way back when.
That TBNN shit is awesome too.
Workouts are limited to 60 minutes due to time. Each exercise is at high rate and output as I can manage.
10 x 6 minute circuits. Each circuit for leg day typically as follows:
1. 1 minute jump rope (I'm moving pretty fast w this)
2. 1 minute lunges (At 30 sec I switch to reverse lunges)
3. 1 Minutes squats (I vary it - sometimes do a thruster - other times half reps - sometimes front squats)
4. 1 minute - Stiff Leg Deadlifts and a calf raise
5. 1 minute - Mountain climbers / Abs. At 30 secs I usually switch. I get 70 mountain climbers in 30 secs - and then do 20 sit ups
6. 1 Minute Rest. (Get a little water)
