Run the session

Hold position for 20 minutes per muscle group. Wear eye protection. For both quad and hamstring in the same day, two separate 20-minute sessions.

Session guidance

The quad and hamstring are large muscle groups — the arm mount's hands-free design is especially useful here. For post-workout recovery, sessions within 30 minutes of training are common in the PBM literature.

Safety & contraindications Do not use over open wounds or active injury requiring immobilisation. Always wear eye protection.
