Reverse Lunge to Single-Leg RDL
Coaching cues
- Step back into a reverse lunge; drive forward to single-leg stand
- From standing, hinge into a single-leg RDL on the same leg
- Return to stand; repeat — continuous hip and hamstring demand
- The lunge loads the quad and hip flexor; the RDL loads the hamstring
Common faults 2
