A. Toes to bar
A1. 1 x max unbroken reps in a 40-second window, Rest 1-minute before A2
A2. 7 sets @ 40% of max reps (unbroken) in A1, Rest 15s between sets (extend to 30/45/60s as needed, see details below)

Please read the notes BEFORE you start so you can be well prepared.

Use A1 to map your max reps in a 40-second window, rest 1-minute THEN perform 7 sets @ 40% of A1 (e.g. if you got 20 reps, 40% = 8 reps, so you would do 7 x 8 reps in this part) with 15 seconds rest between sets. When you can no longer hold the reps with 15 seconds rest, move up to 30 seconds of rest and continue with your sets. Once 30 seconds is no longer enough rest to complete your reps, move up to 45 seconds of rest etc. until you’ve completed all 7 sets.

Example.
A1: 20 reps
A2: 8 reps/15s rest, 8 reps/15s rest, 7 reps/30s rest, 8 reps/30s rest, 6 reps/45s rest, 8 reps/45s rest, 8 reps/DONE.
