Take about 15 minutes to find a max box jump height. Add plates for incremental increases. A running start is acceptable, but both feet must leave the ground at the same time.
The beginning and end of the metcon include 100 double unders each. In between those, you will do a couplet involving power snatches and KB swings. To scale the double unders, you can cut the number down or give yourself a time cap for each set (e.g. 3 minutes of attempts) Power snatch weight should be light enough to ensure proper lockout on reps (no press outs)
