Because weightlifting often pushes your muscles to their limit, you may experience muscle spasms during or after your workout. Many muscle spasms are not serious and can be treated at home. However, if you're frequently experiencing painful muscle spasms when weightlifting, then you should speak with your doctor as soon as you can.
Muscle Spasms
Spasms occur when muscles contract extremely quickly. You may be able to see the muscle twitching or feel it seize up. The muscle might feel hard and even hot to the touch. In some cases, these spasms lead to cramps, which can be very painful. Cramps are particularly common in the calf and thigh, areas you might target with gym weight machines. Weightlifters are also at risk from muscle spasms in the lower back.
Lower Back Spasms
A lower back spasm after weightlifting can be very painful. Lifting weights, particularly if your technique isn't great or you lift beyond your ability, can put a lot of strain on your lower back. In some cases, muscles in the region become swollen and inflamed, and they may even rip slightly. According to the Cedars-Sinai website, this often leads to back spasms. Resting, using ice on the affected area and applying some compression may be enough to heal the damaged muscles. However, you should see a physician if the pain is regular or severe.
Prevention
Try to take a break of at least 48 hours between weightlifting sessions to give your muscles enough time to recover and repair. You should also avoid overloading -- stick to gradual weight increases. Cramps and spasms are also associated with dehydration and a lack of body salts. Ensure you're drinking enough before and during your session, and try to eat more potassium-rich foods such as bananas. If you're lifting in a very hot room, you could increase the risk of spasms. Every session should include a warm-up and cool-down period to help prevent muscle strain.
Treatment
If you experience a muscle spasm while weightlifting, you should stop lifting immediately. Cramps and spasms can often be eased with some simple stretching exercises. If the spasm is in your leg, try massaging the sore area and stretching out your leg. If the spasm doesn't gradually disappear after some stretches, try using an ice pack applied to the problem region. Always see a doctor if your pain doesn't improve.
