A great video of Boxer/ Trainer Ross Enamait from Rosstraining.com.
Try a few of these exercises if you can
SWOD: Max Height Box Jump, 1 RM
Start at a box jump you know you can jump on to, and then begin adding height until you reach your max.
-100 Pull ups
-100 Push ups
-100 Sit ups
Complete all reps of each exercise before moving to the next. Work on accuracy of movement for this workout. Your first rep of each exercise should look exactly like your last rep, albeit a bit slower due to fatigue. If you cannot do an exercise as prescribed, then try to use the most difficult variation of scaling as possible with an eye towards a goal of doing all workouts as written.
Post heights and times to comments.
