article: Back injuries are something every weightlifter should be wary of. Out of all the injuries that are possible from lifting weights, lower back injuries can be particularly painful, long-lasting, and difficult to treat. Thus, the best policy is almost always one of prevention.When you perform a concentration curl, it's OK to bend forward slightly at the hips so that your elbow can reach past the edge of the bench. However, you won't ever want to use a harmful wrenching or twisting motion in your back to complete your exercise — if you have to do this to lift the weight, it's too heavy. For proper spinal health, it's also important to ensure that your workout routine is balanced, including plenty of hip, leg, and core exercises. These muscles aren't directly used for lifting the weight in arm exercises like the concentration curl, but they do support the body and help maintain proper posture, making injury less likely. When it comes to weightlifting, slow and steady wins the race. No matter what you see other people doing at the gym, you should always perform your weightlifting exercises with slow, even, movements, especially if you're doing a high-weight exercise. Moving a weight with quick or jerky motions can make it much more difficult to keep it under proper control, making injury much more likely. Any reputable, experienced trainer will be able to give you the all-important advice that form should always come before weight. In other words, concentrate on doing the exercise perfectly before increasing the weight you're using, and if you can't do the exercise perfectly, try again with a lower weight. As a reminder, for concentration curls, perfect form means keeping your upper arms, elbows, and shoulders motionless and avoiding any jerking or twisting with your back throughout the lift. Any form of weightlifting, including concentration curls, will take its toll on the body. To maximize your results from weightlifting and ensure that you're able to perform as best as you can at the gym, sometimes, not weightlifting is necessary! In general, weightlifters are recommended to avoid training the same muscle group two or more days in a row. Allowing for a day or two of rest (with a full night's sleep after each day) in between bicep-building sessions gives your muscles a chance to recuperate, repair themselves, and, most importantly, grow. Signs of systemic overtraining (in other words, working your entire body too hard, rather than a single muscle group) include elevated pulse in the morning, persistent soreness, high blood pressure, depression, irritability, susceptibility to illness, and lack of motivation.
