Not sure what to call these but I would do these with fighters back in the 90's mostly Judo, Jits, and MMA guys. We use to call them PREDATORS so keep with that, particularly as that is such a mean, harsh offensive word in modern day, safe space, playdoh, pansy, America.
Nevertheless, they are a combo of hybrid good morning/squats with a modified lunge and yes, excessive flexion at the hip.which is intentional. I think they are excellent for developing explosive power at the hip (hybrid Squat/good morning) in positions more inclined to occur in grappling arts, and can build exceptional leg strength with the lunges when base is dropped extremely low. I like relocation of the body, particularly when arriving in closely related fight sport positioning within a set, albeit as these do remain in sagittal plane and are limited. The photos demonstrate proper hip, back, and leg positions at the descent of these lifts. Torso must not go iinto flexion, scaps retracted and you will need some neck extemsion RISK- REWARD is high so if these are done at all do so with very light weight or even a Bulgarian sandbag #FIGHTSHAPE #RICCIFIGHTPERFORMANCE #STRENGTHANDCONDITIONING #EXERCISEPHYSIOLOGY #EXERCISESCIENCE #FIGHTSCIENCE #mma #reebokcombatsports @dymatize @reebok @newyorkfighting #kickboxing #bellatormma #boxing #ufc
