Can You Work Out With Sore Muscles? A Lifter's Rule

Yes, you can usually train a sore muscle. If the muscle feels tight but the soreness eases during your warm-up sets, train as planned. If it's hard to get into position and do the movement, or it really hurts, rest that muscle today and train others.

In three studies, damaging lowering exercise repeated on muscles that had not recovered from the first session did not add muscle damage, and two of them found recovery was not slowed (Nosaka and Clarkson, 1995; Nosaka and Newton, 2002; Chen and Hsieh, 2001). Soreness before every session for the same muscle is a different problem. Ossian's note treats it as a sign to lower that muscle's weekly sets or change how often you train it.

The Basis column says where each row comes from.

Three studies that tested this found no extra muscle damage, and the two that reported on recovery found it was not slowed. All three used lowering-only (eccentric) exercise for the elbow flexors, the muscles that bend the elbow. Nosaka and Clarkson had 12 men who didn't lift weights do 3 sets of 10 lowering reps with a dumbbell set at 80% of their maximal isometric strength (the most force they could produce holding the arm still), then repeat the session 3 and 6 days later. The repeat sessions did not add damage or appear to slow recovery (Nosaka and Clarkson, 1995).

Nosaka and Newton used a lighter dumbbell, at 50% of maximal isometric strength, and repeated the session 2 and 4 days after the first. Strength, range of motion, soreness and a blood marker of muscle damage (creatine kinase) recovered no differently than after a single session, apart from the changes right after each repeat session, when strength fell to the same level as after the first session (Nosaka and Newton, 2002). In Chen and Hsieh's study, 12 college-age men did 30 maximal lowering contractions and then repeated them on each of the next 6 days. None of the damage or inflammation markers rose after the repeat sessions (Chen and Hsieh, 2001).

These were lab studies on one muscle group over about a week. They measured damage and recovery, not muscle growth, so they don't show that training sore helps you grow. They show that a session on muscles that hadn't recovered didn't add damage.

Soreness can still change how the session goes. A review of delayed onset muscle soreness (DOMS) found it can reduce range of motion and peak strength and change how muscles are recruited, which may raise the risk of injury if a person goes back to full training too soon (Cheung et al., 2003). Sweden's health service, 1177, says you can be slightly weaker until the soreness passes (1177). Use the warm-up to judge. If you can get into your normal positions and the soreness eases during the warm-up sets, train. If not, rest that muscle today.

The warm-up test is Ossian's rule. His note says that when a tight, sore muscle eases during the warm-up, performance usually isn't affected. The closest research is about pain. Cheung's review called exercise the most effective way to relieve DOMS pain, though the relief is temporary, and 1177 says light, gentle training can ease soreness (Cheung et al., 2003; 1177). Pain that eases doesn't prove your strength is back,.

Cheung's review found that stretching did nothing for DOMS, and 1177 says stretching and warming up do little or nothing to prevent soreness (Cheung et al., 2003; 1177).

Cheung's review also suggests that athletes who train every day lower the intensity and duration for 1 to 2 days after a session that caused intense DOMS, or train the less affected parts of the body (Cheung et al., 2003). For a lifter, that could mean doing the upper-body session first if your legs are the sore ones, or pushing leg day one day later.

Being sore doesn't show that a session worked. In one study, 110 male students did 12, 24 or 60 maximal lowering contractions of the elbow flexors. The groups that did 24 or 60 lost more strength and recovered more slowly than the 12-contraction group, but their soreness when the muscle was pressed or flexed was not significantly higher. Only soreness on stretching was. The authors concluded that soreness is a poor reflection of muscle damage (Nosaka et al., 2002).

Damage isn't what builds muscle either. A 2018 review concluded that training that caused little muscle damage built about as much muscle and strength as training that caused a lot. The authors argue that over roughly the first four sessions of a new program, most of the measured increase in muscle size is swelling from damage. Modest growth follows after about 10 sessions, and clear growth after about 18 (Damas et al., 2018).

Feeling less sore a few weeks into a program therefore doesn't mean it has stopped working. To see whether it works, check your log for weights and reps that go up over time. The progressive overload guide covers what to look for.

DOMS is most common when people come back to training after a break, and it is also common when they first try a new kind of exercise. Lowering, or eccentric, work causes more muscle micro-injury than other muscle actions (Cheung et al., 2003). According to 1177, soreness is usually worst one to two days after the session and is usually gone within a week (1177).

One session of lowering exercise protects the muscle against damage from later sessions of the same kind, an adaptation called the repeated bout effect (McHugh, 2003). Cheung's review suggests bringing in new exercises over 1 to 2 weeks to limit how much they disrupt training (Cheung et al., 2003).

The warm-up test assumes that training a sore muscle is rare. If the muscle is still sore every time the program comes back to it, Ossian's note says to look over the programming. Overlapping soreness on a regular basis probably isn't getting you the best results, and the fix is to lower the weekly training volume for that muscle or change how often you train it. The guide to training frequency covers how to spread sets across the week.

GainsLog's program builder rates a plan against a weekly set range for each muscle, for example 5 to 12 sets a week for back and quads in its default setting. The plan preview flags "High muscle volume" when one workout has more than 5 working sets for one muscle group, such as chest, back or quads. The free volume calculator uses the same ranges, so you can look up the weekly range for each muscle and compare it with what your program gives.

Normal soreness feels stiff and tender in the muscles you trained and usually fades within a week. Contact a doctor if it gets worse or hasn't gone after a week (1177). Dark, red or cola-colored urine can be a sign of rhabdomyolysis, a breakdown of muscle tissue that needs prompt medical care. MedlinePlus lists severe exertion as one cause, and muscle weakness and tenderness as other symptoms (MedlinePlus).
