You don't need a wrestler, but a S&C coach who understands the physical needs of the sport, to taylor the lifting program. They should have a specific off season, pre-season, and in season program, all mandatory. Need to blend traditional barbell lifts for strength, with things like kettlebell and Bulgarian bag exersizes for strength endurance and grip strength. Body weight exersizes with rings, chin bar, climbing rope also needed for total body strength in wrestling. The body gets stress put on it in odd positions in wrestling, and trying to mimick that with barbells and dumbells is dangerous. Having great core strength is very improtant, and pulling should be emphasized more than pushing, but not to extent of causing muscle imbalance, which leads to shoulder problems. This can get complicated fast, which is why you need a pro, not just an ex wrestler who wants to break into coaching.
