Just going through the reps in a lift is not enough. Without complete control over your body and the motions of the particular lift you are focusing on, you won't be maximizing the potential energy your body has to offer, "You want the most stable platform from which to produce force as you can," Mighty Joe Stankowski tells Men's Fitness. "The more stable the foundation [of your body], the more force you can produce."
1. START FROM THE BOTTOM UP
Find a way to provide a stable and strong base from which to work from. If you're benching, "clench the bench." Contract your glutes so that you get a firm hold on the bench. Dig your feet into the ground as well, dialing them outward so that you can get a better grip. The same goes for other lifts like the squat and deadlift; find a weight to gain greater stability from your feet and work your way up, focusing on a stiff core and a tight back.
2. GET A GRIP
"Squeeze the hell out of the bar," Stankowski says. "Squeeze the hell out of it like you're going to crush it. Whether it's a kettlebell, dumbbell, or barbell, we want to get tight, and tightness starts with the grip." Chalk and grip sprays can also help gain traction and control over the bar, but try to avoid straps and gloves that tend to bunch up and numb the feel for the bar.
3. HOLD YOUR BREATH
Stankowski recommends holding your breath while lifting. Think of it like a slightly deflated ball—when you pump more air into it, it becomes stiffer and more resilient. The same is true with your body. "(Dr.) Stuart McGill talks about this concept of super stiffness," says Stankowski, "where you're using all the layers of your abdominal core muscles, kind of like how plywood has strands that go in opposite directions, layer over layer of these opposing strands, our abs kind of work like that too. When the overlapping muscles of your core contract, they work together to provide cumulative support. If you inhale, the air pressure from within your body meets the "plywood" resistance of your core muscles, creating a powerful combination of internal and external forces that produces an overall "super stiffness" in your core, transforming your core into a solid granite base of support.
