The Olympic Complex.
The Olympic Complex is a hang clean progression which includes: RDL's (Romanian deadlift), power shrugs, highpulls, and hang clean.
You perform three (3) of each in order. The RDL's fire your hamstrings to get them ready for the clean. The power shrugs get your body ready to produce short bursts of power from your legs. The Highpulls prepare you for pulling weight with your arms but also teach you to make the weight move from the power in your legs more. The Hang Clean is the final product, putting it all together to form a powerful, safe, and efficient Hang Clean!
