Video clip illustrating proper form of the bicep curl exercise. The key thing is to be slow and deliberate, no swinging allowed. The elbows should remain pinned to your side and not move forward or backward during the exercise.
As with any dumbbell exercise, form is key if you want to maximize your muscle building efforts and minimize the chance of injury. Don't use too much weight, if you can't do the exercise slowly then you need to go lighter. Count aloud "one onethousand, two onethousand, three onethousand" on the way up and the way down, if you cant do this on this exercise then you are using too much weight. The reason this exercise method maximizes your muscle growth is because it confines the motion to the muscle you are trying to work out, if your body squirms, swings, and kicks, all you are doing is taking the focus away from the muscle you are trying to exercise.
Anyone can be healthier, have more energy, sleep better, and feel better about themselves through bodybuilding. Bodybuilding doesn't have to be expensive or take a lot of time, gyms are great but home workouts can save you time and money. A cheap dumbbell set from a garage sale or walmart is all it takes to get started with your home workouts.
