Muscle recovery: what actually helps
Sleep and food beat gadgets
Coach Julien Marest

In simple terms
Ice baths, massage guns and compression have their place, but the basics do more.
Why muscles hurt two days later
Delayed onset muscle soreness peaks 24 to 72 hours after unfamiliar effort, especially after downhill running or lowering heavy weights. It comes from microscopic damage and the inflammatory repair that follows. It is normal and it fades.
What has the strongest effect
- Sleep: 7 to 9 hours is when most tissue repair and hormone release happens.
- Enough calories and protein: recovery is a building process; under-eating stalls it.
- Light movement: an easy walk or gentle cycling the next day eases stiffness better than complete rest.
What helps a little
Massage and foam rolling reduce the feeling of soreness. Compression garments may slightly speed the return of strength. Cold water immersion lowers soreness but, used right after strength training, may blunt some muscle-building signals, so keep it for competition days rather than every session.
The real limiting factor
Most people do not need more recovery tools. They need a training load that rises gradually, with at least one genuinely easy day each week.
The words explained
Medical terms used above, in everyday language.
- Inflammation
- The body's reaction to injury or irritation: redness, swelling, heat or pain.
- Hormone
- A chemical messenger made by your body that tells organs what to do.
When should you see a doctor?
- Your symptoms last more than a few weeks or keep coming back.
- They get worse quickly, or stop you doing everyday things.
- You notice sudden pain, breathing trouble, fainting or bleeding — seek urgent care.
- You already take medication and want to change anything about it.
