TRX Twisting Jackknife
The TRX jackknife with a twist: the knees are drawn in toward one shoulder, then the other, so the obliques take the tuck.
How to do it
Setup
High plank with the feet in the TRX cradles, hands under the shoulders.
Steps
- Draw both knees in toward one shoulder, hips turning.
- Push the legs back out to the straight plank.
- Tuck toward the other shoulder next.
Common mistakes
Straps swinging after each tuck: pause in the plank before the next. Shoulders drifting behind the hands: keep them over the wrists. Knees coming straight in: the twist is the point; turn the hips.
Breathing
Exhale on the tuck, inhale extending.
