CoreTRX
From a TRX plank, the hips pike up toward the ceiling, requiring the core to control the transition and resist extension both in the plank and pike phases. A staple TRX core progression.

Contraindications
Wrist or shoulder pain in a high plank — reduce range or use fists.Setup
Feet in TRX foot cradles, start in a high plank position with hands under shoulders.
Execution
- 1Begin in a stable TRX plank with the core braced
- 2Drive the hips up toward the ceiling by flexing at the hips, keeping legs relatively straight
- 3Pull the knees toward the chest through the core, not by yanking with the arms
- 4Pause briefly at the top of the pike
- 5Lower back to the plank position with control
Key cues
- Hips lead the movement, not the shoulders
- Keep arms locked, only the hips travel
- Squeeze the abs to pull the pike, don't just let momentum swing it
- Control the return to plank, don't crash down
Common faults
- Using arm swing or momentum instead of ab-driven hip flexion
- Losing the plank position as the pike returns
- Not achieving true hip flexion, just bending the knees
- Rounding excessively through the upper back
Tweaks
- Perform single-leg pikes for more difficulty
- Slow the tempo to 3 seconds up, 3 seconds down
- Add a pause at the top of the pike
