Most people have experienced a muscle spasm, or cramp, at one time or another. Sometimes it wakes you up out of dead sleep or it can start when you are exercising or just watching television. Weightlifting can cause muscle spasms, too, but by making a few changes you may be able to avoid them.
Muscle spasms can occur from weight lifting, but stretching can help.
Understand Your Spasm
A muscle cramp, or spasm, is when a muscle gets tight on its own without you contracting it, according to Medline Plus. The muscle may feel hard and does not relax. Often stretching gently and massaging the area can help it relax. The repeated contractions of weightlifting can cause muscle spasms, as well as nutrient deficiency or dehydration that can accompany strenuous workouts such as resistance training.
Take It Easy
If you are getting muscle spasms regularly after weight-lifting workouts, you may be pushing too hard. You want to challenge your body, but if you go too hard too quickly you can end up injuring yourself - not to mention making your workout more unpleasant than it needs to be. Try decreasing the resistance you use by 10 percent and see if the frequency of spasms decrease. Also, make sure you warm up properly before you work out, and stretch the muscles you work at the end. Take adequate time to recover between workouts as well. A muscle needs at least 48 hours rest between workouts. If your sore, you need a little longer.
Take Small Sips
You could be dehydrated without ever realizing it, and that can contribute to spasms. Sweat is a by-product of intense workouts such as weightlifting. You need to replace those fluids, otherwise your body cannot function properly. Muscle tissue is mostly water, and if you dehydrate even slightly it can cause problems. The American Council on Exercise advises 125 and 91 oz. respectively for men and women each day. If you exercise strenuously, you may need to drink a little more. So sip water throughout the day.
Improve Your Balance
Low levels of electrolytes such as potassium and sodium can also contribute to muscle spasms. These electrolytes are lost through sweat, and if you're sweating a lot or exercising for a long time, you need to replace them. Sports drinks have electrolytes that are easily absorbed by the body. You can drink these during your workouts or immediately after to prevent electrolyte imbalance. They also add re-hydration of fluids lost during weightlifting, or cardio workouts.
