These days I see many fitness professionals at your typical Globol Gym who seem more concerned with entertaining clients than getting results, often dismiss progressive overload with randomization. Their train of thought usually goes something like this: Why deadlift when you can do one-legged kettlebell deadlifts on a BOSU ball?
My question is, how can you continually overload training if it is totally randomized? Put simply, you can’t!! The idea of overload is to make training harder but keep the same end game in mind. Doing squats on an unstable surface may make sense for an advanced alpine skier, but it’s downright debauchery for anyone hoping to make serious gains in size and strength.
Why? Simply, balance is the limiting factor; you cannot produce enough mechanical tension—the primary mechanism to spark hypertrophy—when balance is the primary concern. High amounts of tension are produced by lifting heavy weights.
Be smart with your technique, and put strength training first. Trying to build huge traps with shrugs? It would not make sense to overload your training by taking off your hand straps; the goal is to build the traps, not the grip.
Overload must be approached using sound scientific training and common sense. Sure, you can do dumbbell curls while you lunge, but don’t con yourself into believing you are providing any sort of serious overload to your legs. Want real overload? Hit the squat rack!!
