2B Suspended Jackknife

Sets: 3 Reps: 5, then 20-second hold

Attach a suspension training apparatus to a sturdy object and place your feet in the loops. Get into a pushup position [1], and then bring your knees to your chest [2], and back again. That's one rep. After you've completed five reps, hold the knees extended position for 20 seconds.
