How Iridium Programs This

Iridium programs the TRX Bridge as a high-volume accessory that targets the glutes and hamstrings while minimizing axial loading on the spine. Since external resistance is difficult to scale, the AI relies on RPE tracking to ensure you reach adequate intensity through increased repetitions rather than load. Iridium prioritizes this variation when your 7-day training history suggests your lower back has not fully recovered from recent heavy compound lifts.

Form Cues

Place your heels firmly in the foot cradles
Drive your heels down to lift your hips
Squeeze your glutes hard at the top
Keep your core braced and ribs tucked
Maintain constant tension on the TRX straps

Don't

Don't arch your lower back excessively
Don't let the straps 'saw' back and forth
Don't push through your toes
Don't allow your hips to sag at the top

Common Mistakes

Hyperextending the lumbar spine
Uneven pressure on the straps
Using mostly hamstrings instead of glutes
Rushing the lowering phase
Relaxing the core at the bottom

Muscles Worked

This exercise primarily targets the gluteus maximus, which works to extend the hips against gravity and instability. Your hamstrings act as powerful stabilizers to keep your knees bent and feet secured in the straps, while your deep core muscles engage to prevent rotation or swaying.
