Weight training do's and don'ts

The weight-training can have an exciting time in the gym if they follow certain rules and avoid one or two machines. The machines to avoid in an upper body workout, except perhaps on the day of competition, would be to avoid a military press. A military press machine can often lead to impingement syndrome of the shoulder with pain while trying to do overhead work. Instead of using the military press, because it is important to exercise those muscles, you can get the same results by doing an incline press.
When doing upper-body strengthening, you want to keep your hands in your peripheral vision at all times. If you can't see your hands and fingers, the benefit of that exercise has been shown to be minimal. So if you are grabbing the bar and pulling it down behind your head, you should not go further to the point that you can't see your fingers and rather perhaps you should put it in front of you.
Most of the equipment to exercise your upper body has handles that are placed for a generic 5-foot-8-inch to 5-foot-10-inch man with a certain build. Even though the handles are put at a certain distance it is important to grab the bars at a shoulder-width distance apart. Doing wide grip lifts, except on the day of competition, offer little advantage compared to a narrow grip lift and a narrow lift grip will not injure certain parts of the shoulder.
In the lower body you should try to avoid seated leg-extension exercises. When you do seated leg-extension exercises to strengthen the medialis the patella tendon, often in people too numerous to count, can't tolerate the exercise because of the weight and the stress that's placed at the ankle. Patients come in with either arthritis of the kneecap or patella tendon pain. Simply stopping the exercise, that is, the leg extension, and substituting a one-third knee bend with an elastic cord to offer resistance, can give the same buildup of muscles without the detriment of injury.
Most exercises in the lower body should be done with a short arc eccentric load, because squatting down fully, while exciting to the trainer, offers no advantage for the muscle and only allows for injury to occur
