Here's a little beauty I devised this evening which took my heart rate to 170bpm and torched my muscles - all in the name of lactate training.
I've been messing with such circuits for the last 8 weeks as part of my fat loss programme. This is the best one I've entertained to date and wiped me out a full 10mins sooner than I've managed on previous lactate sessions. Credit to Scott Abel and Nick Tumminello for posting some of the exercises on T-Nation (links below):
A1) Alternating jumping split squat - x12 reps
A2) Push-up - x15-18 (tried medicine ball crossover variety but sadly died a death after 1 set)
A3) Compound row - x15
A4) Angled deadlift press - x12
A5) High pull - x12
Exercises done explosively. All done back-to-back circuit style wth 90s RI between circuits. I managed four rounds, and that included dropping A5 on the last two!
