When doing any workout or exercise, technique and form are imperative. Not only do the best results come from working the muscles that are meant to be worked but the likelihood of injury will be lowered. I can’t tell how many times I’ve used too heavy of a weight and injured another part of my body trying to jerk or help lift that weight. If I feel myself using a different muscle than the one I’m supposed to be working, I simply lower the weight to get proper form and do the exercise I’m supposed to be doing. The main benefit of this is that my strength will increase and I will get the results I’m supposed to be getting while reducing the risk of injury.
Of course this is not to say that as a person is first learning about fitness or just getting started that their form will be perfect…It Won’t!! The key though is learning a move or routine that you’re incorporating and getting your body used to doing that particular movement. Once you have the form down you can really engage the proper muscles and the results will follow.
One thing to remember is even without proper form, if you’re doing anything, you’re doing more than a person sitting on the couch so get moving. Everything else can be learned and refined if you just get up and do something.
