Try not to put your body through unnatural movements, like arching a lot or lifting with a curved spine.
Concentrate
Working out while you’re distracted or tired you’re more likely to get injured. More concentration equals to more poundage and that will lead to more growth. If you won’t pay attention, you can get hurt.
Back protection
If you have back problems, the first thing you should do is get a weight belt. It will limit your movement, thus maintaining proper form, as you gradually get more tired during a set. It helps you aim the muscle you want to exercise and reduces the risk of injury.
:: Injuries ::
Safety
Weight machines are usually safer than free weights because the person isn’t grasping onto the weights himself. It won’t fall therefore no injury.
Prevent injuries
Stretching increases flexibility thus making you less prone to injuries. The explanation for this is that a muscle/tendon group with a bigger range of motion passively, will experience tears less when used actively.
