TRX Single Leg Squat
The TRX Single Leg Squat is a unilateral lower-body exercise that uses suspension straps to assist with balance and depth. It primarily targets the quadriceps and glutes while improving stability and correcting muscle imbalances.
Because this exercise relies on self-regulation of arm assistance, the AI analyzes your RPE (Rate of Perceived Exertion) to ensure you aren't pulling too much with your upper body. If your recovery metrics (HRV and sleep) indicate high fatigue, your balance may be compromised; the app can detect this and suggest a more stable regression like the TRX Split Squat to maintain safety. Additionally, the app tracks left-vs-right performance over time to identify strength asymmetries that may require targeted volume adjustments.
Form Cues
- Keep your elbows slightly bent and tension on the straps
- Extend your non-working leg straight out in front of you
- Sit your hips back and down like aiming for a chair
- Drive firmly through the heel of your standing foot
- Keep your chest lifted and eyes forward
- Don't pull yourself up completely with your arms
- Don't let your standing heel lift off the floor
- Don't allow your standing knee to collapse inward
- Don't round your lower back at the bottom of the movement
Common Mistakes
- Over-relying on arm strength
- Knee caving inward (valgus)
- Rounding the spine
- lifting the heel
- Descending too quickly
Muscles Worked
This exercise is a powerhouse for the quadriceps and glutes, forcing one leg to manage your body weight without the stability of a bilateral stance. It also heavily recruits the core stabilizers and hamstrings to maintain balance and control the descent, making it excellent for fixing strength asymmetries.
