Two days ago, I was introducing one of my friend to weight lifting. Actually, I’ve trained several of my friends because a) They are too cheap to use the services of a peronnal trainer and b) personnal trainers usually SUCK!
I always insist on perfect form and tempo. To make a long story short, I don’t let my friends get away with a bad form and it can take alot of time before they get it. I don’t care because it’s too important. So I was with my friend and he couldn’t keep his elbows glued to his body while performing barbell curls. He also had a tendency to move his upper arm to help the lift, and it pissed me off. He did the same thing while performing triceps pulldown. So I had the clever idea to stick 2.5 lbs. plates under his armpits, and suddenly, he had perfect form and he was screaming in pain! I felt his muscles and they were working big time! So I have 2 questions:
1- Is the plates-in-the-armpits a common technique?
2- Do you have other good ideas for preventing cheating in any exercise?
