Muscle Recovery: What the Reviews Found

Quick answer

Recovery trials track soreness for up to 96 hours, and in one trial muscle function was still lower 48 hours after sets taken to failure. A review of 99 studies ranked massage first for lowering soreness. Sports nutrition groups put total daily protein first, in 20 to 40 g servings every 3 to 4 hours.^1,2,3,4

Key facts

In a review of 99 studies, massage ranked first for lowering soreness and perceived fatigue.³
Foam rolling after exercise slightly lowered perceived soreness, and the authors called its effects on performance and recovery minor.⁵
A Cochrane review of 17 small cold-water trials found lower soreness than with rest at 24 to 96 hours, but in a 12-week trial of 21 men, cold water after each session was followed by smaller muscle and strength gains.^1,6
A review of athletes linked lack of sleep to lower submaximal strength and endurance.⁷
The International Society of Sports Nutrition (ISSN) calls total daily protein, spread through the day in 20 to 40 g servings, a primary area of emphasis for people who exercise.⁴
NIH says people recover most quickly on an adequate diet with enough fluids and proper training, and describes the recovery research on several popular supplements as limited or hard to judge.⁸

How long does muscle recovery take?

There is no single clock. How long muscles stay sore or weak depends on how hard the session was, how new it was and how close to failure the sets went. Soreness is most common after a break from training or when you start a new activity, and exercise with a lowering phase causes it more often and more severely than other kinds.⁹

What recovery studies measured, and for how long^1,2,9
Study	What was measured	Time window
10 men doing sets of bench press and squat, some taken to failure	Jump height and bar speed	Still lower at 48 hours after the hardest protocols
17 small trials of cold-water immersion	Soreness ratings	Followed at 24, 48, 72 and 96 hours
A review of soreness for people who train every day	Intensity and length of training	Ease off for 1 to 2 days after a session that leaves you very sore

These are windows from particular studies, not a schedule. Muscles also stay responsive to protein for about a day after lifting.^10,11

Muscle stays more responsive to protein for about 24 hours after resistance exercise, and NIH notes that muscle protein building rises for up to a day or two.^10,11

Muscle recovery after a workout: sleep, protein and fluids

Sleep: a review of athletes linked lack of sleep to slower reaction time and lower submaximal strength and endurance, and longer sleep to better reaction time, mood and sprint times.⁷
Protein: the ISSN calls total daily protein, spread through the day, the first priority for people who exercise, with servings of 20 to 40 g every 3 to 4 hours, and says high-quality protein within 2 hours after exercise stimulates muscle protein building.⁴
Carbohydrate: for people who must be ready to train again in under 4 hours, the ISSN lists 1.2 g per kg of body weight per hour for refueling. The ISSN gives this only for cases where rapid restoration is required.⁴
Fluids and diet: NIH's Office of Dietary Supplements says people recover most quickly when they eat a nutritionally adequate diet, drink enough fluids, are physically fit and are properly trained.⁸

A meta-analysis of randomized trials found that protein taken within an hour before or after exercise did not significantly add strength or muscle size; total daily protein was the strongest predictor of muscle gain.^11,12

Our guide to sleep covers the sleep research in more detail.

Muscle recovery foods

No source we read names a single recovery food. The sports nutrition groups point to total protein across the day and an adequate diet overall, so foods that supply protein are the practical starting point.^4,8

One ounce of meat, fish or poultry, 1 large egg, a quarter cup of tofu, or half a cup of cooked beans or lentils each gives about 7 g of protein.¹³

NIH says most athletes can probably get enough protein from food, and that protein powders and protein-fortified foods can help when they cannot. It sees no benefit in eating more than the recommended amounts.⁸

Muscle recovery techniques: massage, foam rolling and cold water

What reviews found for soreness^1,3,5,9
Technique	What the review found	Study
Massage	Ranked first for lowering soreness and perceived fatigue among 99 studies	Systematic review and meta-analysis
Active recovery, compression garments, water immersion, contrast water, cold exposure	Each lowered soreness by a small to large amount	Same review
Foam rolling after exercise	Slightly lowered perceived soreness, with effects on performance and recovery called minor	Meta-analysis of 21 studies
Cold-water immersion	Lower soreness than rest at 24 to 96 hours, pooled from small trials of low quality	Cochrane review of 17 trials
Stretching	No effect on soreness in the review's findings	Narrative review

Cold water has a trade-off for people who lift to build muscle. In a trial of 21 active men training twice a week for 12 weeks, those who sat in cold water for 10 minutes after each session gained less muscle and strength than those who did light active recovery, and the authors suggested reconsidering cold water as a regular recovery habit.⁶

These reviews looked at massage and the other methods in general, not at who provides them or where, so they cannot say what to look for near you. A doctor or licensed physical therapist can advise on local options.³

Muscle recovery supplement: what NIH says about the research

NIH's Office of Dietary Supplements says only a few supplements have enough evidence for certain kinds of exercise, and that people recover most quickly on an adequate diet with enough fluids and proper training. For recovery specifically, its consumer fact sheet describes the research on several popular supplements this way.⁸

How NIH describes the recovery research⁸
Supplement	What the fact sheet says about recovery
Arginine	Little scientific evidence for helping tired and sore muscles recover
BCAAs	Not much scientific evidence, and eating protein foods already supplies them
Glutamine	Few studies, with either no effect or a small one
HMB	Seems to speed recovery from exercise hard enough to damage muscle, but the research is hard to compare across ages, fitness levels and doses
Tart cherry	Limited research with variable results, though some studies suggest it might shorten strength recovery and ease soreness

We do not rate supplements for recovery on this page. Protein and creatine have guides of their own, linked below.

Muscle recovery creams

We did not find a systematic review of creams or rubs for exercise soreness to cite, so this guide does not rate them. The reviews above cover massage, active recovery, compression and immersion.

Stop and ask a doctor if

MedlinePlus says to contact a provider if muscle pain lasts more than 3 days, if the pain is severe and unexplained, if there is swelling or redness around a tender muscle, or if the pain began after starting or changing a medicine such as a statin.¹⁴

Dark, red or cola-colored urine, passing less urine than usual and general weakness after very hard exercise are symptoms MedlinePlus lists for rhabdomyolysis, a breakdown of muscle that can damage the kidneys. It names severe exertion such as marathon running or calisthenics among the causes, and says to contact a provider with these symptoms.¹⁵

If you are asking about recovery peptides such as BPC-157, FDA's page on bulk drug substances with potential significant safety risks says compounded drugs containing it may pose a risk of immune reaction for certain routes. It also says FDA found no or only limited safety information for the proposed routes, so it cannot say whether the drug would cause harm. The page lists BPC-157 among substances whose nominations for compounding were withdrawn. Ask your doctor or pharmacist before using any such product.¹⁶

Questions people ask

How long is muscle recovery time after a workout?

There is no fixed time. In one trial, jump height and bar speed were still lower 48 hours after the hardest sets, and soreness trials followed people for up to 96 hours. MedlinePlus advises contacting a provider if muscle pain lasts more than 3 days.^1,2,14

What speeds up muscle recovery after a workout?

In a review of 99 studies, massage ranked first for lowering soreness and fatigue, and active recovery, compression garments, immersion and cold exposure also lowered soreness. Sleep, total daily protein and enough fluids are the basics named by sports nutrition groups and NIH.^3,4,8

Is there a muscle recovery supplement that works?

NIH's consumer fact sheet describes little scientific evidence on recovery for arginine and BCAAs, no effect or a small one for glutamine, and limited or mixed research for HMB and tart cherry. It says people recover most quickly on an adequate diet with enough fluids and proper training.⁸

What are the best muscle recovery foods?

No source we read names a single recovery food. The ISSN puts total daily protein first, with 20 to 40 g servings every 3 to 4 hours, and about 1 oz of meat, fish or poultry or 1 large egg supplies about 7 g of protein.^4,13

Do muscle recovery creams work?

We did not find a systematic review of creams for exercise soreness to cite, so we do not rate them. The reviews we cite looked at massage, active recovery, compression garments and immersion.³

What does FDA say about muscle recovery peptides?

FDA's page on bulk drug substances with potential significant safety risks says compounded drugs containing the peptide BPC-157 may pose a risk of immune reaction for certain routes, and that it found no or only limited safety information, so it cannot say whether the drug would cause harm. Ask a doctor or pharmacist before using any such product.¹⁶
