Level: Foundation
Primary: Abs
Movement: Isolation
Type: Functional Fitness (Obstacle & Hybrid) Light Activity

Target muscles
The obliques drive the rotational element. The rectus abdominis braces. The hip flexors lift the knees. The shoulders hold the support position.
How to perform
Setup
Place feet in the suspension straps. Assume a push-up position.
Execution
Drive both knees toward one shoulder to engage the obliques. Return to the start. Repeat on the other side. Keep hips stable.
Common mistakes
- Hips dropping.
- Not bringing knees fully to the shoulder.
- Going too fast.
- Forgetting to alternate.
- Soft trunk.
Progressions and regressions
Regress to standard suspension crunches. To progress, work for time.
Programming notes
Rotational trunk work. 3 sets of 8-12 per side, twice a week.
