I know a doctor who works out in my gym who is around my dad’s age, so he’s probably late 40s. I get so aggravated watching him workout because everything he does is only half a movement with heavy weight. But it works. He’s got really good size despite his lack of technique. This just shows that something is always better than nothing as long as you don’t hurt yourself in the process.
For example: I can only squat with a wide stance. I have very high arches. This is not the form you’ll see on a cover of Muscle & Fitness, but hey- it works for me fine. What happened when I tried squatting with my feet closer together as “good form” suggests? I cracked my back and ended up unable to walk for a few days. So using “correct” form was acutally “wrong” form for me.
Another example is people who think touching your chest with the barbell during a bench press is “correct form”. It’s correct alright- correct “BS”. What if you have longer arms in relation to your body and a very flat chest? You would be unable to touch your chest with the bar- in fact touching your chest may lead to injury.
How wide is your stance? I’m not sure how close a Muscle and Fitness would tell me to keep my feet. I go slightly past shoulder width apart but I don’t really consider that close or very wide. I see some guys go a bit wider than me as well and it works for them. (By works I mean 500+)
If your arms are long you’ve just got more work to do. Bring the bar to your chest.
