Are you going to the trouble, preparation and expense of getting yourself to the gym, then sabotaging your workouts by ignoring proper form?
Proper form makes all the difference between progress and, well, plateauing, meaning, no progress. Proper form is not a mystery, yet many are clueless on this.
Numerous times I have seen someone working out next to a person who is admirably fit, and doing the exact same exercise—for instance, a guy doing biceps curls who has a terrific set of arms. Yet the person next to him doing the same exercise seems totally unaware that he might learn something from Mr. Big Arms. He is so checked out that it doesn’t seem he even realizes he is performing the same exercise as Mr. Big Arms, much less he might watch, imitate and learn.
My point is most people using bad form have no idea. It doesn’t even occur to them they are using bad form. It doesn’t occur to them that the guys with the awesome bodies are doing something they are not, and therefore they might pay attention to these achievers and learn by example.
If you haven’t made progress within the last month, you need to change it up. When you use proper form you’ll see a big difference, not in the following month, but that very same day at the end of your workout by achieving a good pump. If your arms don’t look noticeably improved immediately following your arm workout, it’s because your form is poor.
Thanks to YouTube and its thousands of workout videos, there is no longer any excuse for poor form, yet poor form remains endemic in gyms and home workouts. Instead of looking for a “new” exercise due to frustration over lack of progress, know that every classic exercise works wonders if performed with proper form.
