There are several reasons why you might experience pain in your forearms during or after your workout. If you work out with weights, experiencing a burn as you approach to fatigue, and occasionally feeling sore the following day, are a matter of course. However, injuries caused by resistance training are relatively common, and you should consult your physician if you have pain that is intense or persists.
Delayed Onset Muscle Soreness
Delayed onset muscle soreness, or DOMS, is the soreness that you begin to feel 12 to 48 hours after an intense workout. Soreness in your forearms, following a strenuous bout of biceps training, is caused by micro-damage to the muscles and is not usually cause for concern. However, you should avoid training your biceps or forearms again until the DOMS has subsided. Massage and stretching exercises for the forearms can help to alleviate the pain associated with DOMS.
Pain in your forearms can also signal an injury in the area. It is important to learn the difference between soreness and a legitimate injury. Common injuries of the forearms include strains, sprains and tears. If the pain you experience in your forearms during biceps curls is sudden or severe, stop training immediately and seek medical advice. Warming up your forearms with some light sets and stretches, before starting your main workout, can help you avoid injury.
