One of the best exercises to teach pulling straight, is this "Trap bar pulls" While I rarely see this apparatus in China, I do see them doing dumbbell pulls which mimics the pattern of being centred. The benefits I've experienced and tested are; 1. Easier to understand "Sit your hips, and use your legs" to stand during the first pull 2. Stability in the feet which help build stronger arches 3. Stand on a pair of 25KG plates, use the bottom handle and do 20 reps for the quad pump of your life 4. Have back and knee pain and can't understand sumo deadlifts? Here's your answer 5. Want to answer the question in your head of "How do I pull straight and close??", again this is your answer The trap bar is relentless in demanding you stay centred. Raise your butt a bit and you get thrown forward. Lean back too soon and you fall backwards. Refuse to address your lateral imbalance, and find yourself helicoptering when you lockout. Let the bar drift away a bit and find yourself taking a step forward to save it. Its a brilliant tool I usually do them with 8 reps/6 sets at about 70% of my squats 1RM before squats. They help me really groove the positions I need to be in before I squat #lifthardwl #weightlifting #chineseweightlifting #crossfitweightlifting #crossfit #pulls #deadlifts #legs
