Lower Body Assistance

Equipment: TRX
Difficulty: Intermediate
Movement Pattern: Knee Flexion

The TRX Hams Curl is a suspension-training exercise that combines knee flexion, hip extension and trunk stabilization within a single movement. Unlike traditional machine-based hamstring curls, the suspension setup requires continuous activation of the core and pelvic stabilizers to maintain proper body alignment throughout the exercise. The movement primarily targets the hamstrings while simultaneously challenging the glutes, abdominal musculature and lumbopelvic stabilizers. Due to the unstable nature of suspension training, it serves as an effective alternative to physioball and slider variations, developing posterior-chain strength, motor control and dynamic stability at the same time. For these reasons, it is commonly used in athletic development, injury-prevention programs and functional lower-body training.

Coaching Cues

Keep the hips elevated throughout the exercise. Brace the core before initiating the movement. Maintain a straight line from shoulders to knees. Pull the heels toward the glutes under control. Avoid excessive movement of the straps. Keep the pelvis stable throughout the set. Control the eccentric phase completely. Maintain steady breathing without losing core tension.

Common Mistakes

Allowing the hips to drop during the movement. Compensating with excessive lumbar extension. Failing to maintain abdominal tension. Performing repetitions too quickly. Limiting range of motion unnecessarily. Allowing uncontrolled strap movement. Losing alignment between the trunk and lower body.
