I bought a heart rate monitor today to test my various training methods. I did the double swings, snatches, cleans and presses, front squats and TGU's, fast.
Then I did 13 minutes on the ropes 30/30 protocol.
Warm ups/ cooldowns were Z-NWU, clubs and gada stick.
Heart rate got up to 148 bpm after the fast five TGU's. After the ropes it was 158 bpm, I really had to push it to get it that high. That's 90% of my max.
