How much rest do my muscles need between workouts as I get older?
Getting older does not call for more rest, but for more regular training: at least two resistance-training sessions per week, supplemented with adequate protein, is the best-supported approach for counteracting muscle loss.
Training twice a week is the best-supported approach for muscle growth in healthy adults. Three times a week yields the greatest strength benefit. This means your muscles get an average of 48 to 72 hours of rest between two sessions, which for most people translates to a training schedule of Monday-Thursday or Monday-Wednesday-Friday.
As you get older, your muscles respond less effectively to both exercise and protein. This is called anabolic resistance: the stimulus that is already enough for muscle building in a younger person is insufficient in an older one. That may sound like a reason to take more rest, but the opposite is true. Ageing actually makes muscle loss during inactivity faster and more pronounced. Longer rest periods are therefore a greater risk than they are for younger people, not a smaller one.
Anabolic resistance can be partially offset. A higher protein intake of 1.2 to 1.6 grams per kilogram of body weight per day, combined with resistance training, modestly but measurably improves muscle building in people aged 65 and over. The effect is modest, but every contribution counts when you are working against a biological disadvantage.
In practical terms, this means: as you get older, stick to at least two training days per week, and fill rest days with movement rather than complete inactivity. Complete rest is rarely the right answer. If you suffer from prolonged muscle soreness or notice that you are clearly recovering more slowly than before, discuss this with a physiotherapist or sports physician, as it may indicate overtraining or nutritional deficiencies.
Based on a meta-analysis on training frequency and load (PMID 37414459), a review on anabolic resistance and inactivity (PMID 35476500), and a meta-analysis on protein intake in older adults (PMID 35187864).
What is the best type of exercise to prevent muscle loss after 60?
Strength training is the best-studied approach to preventing muscle loss after 60. Combining it with balance exercises and sufficient protein produces the greatest results.
Why is muscle strength so important for healthy ageing?
Muscle strength is one of the best-supported pillars of healthy ageing: losing it increases the risk of falls, disability and premature death, while resistance training demonstrably reduces those risks. So do regular strength exercises, and if you are unsure how, discuss it with a physiotherapist.
How much muscle strength do you lose per year after the age of fifty?
After the age of fifty, you can quickly lose 3 to 4% of leg strength per year, far more than muscle mass alone would suggest. Strength training, combined with adequate protein intake, is the most effective way to counter this.
Can you regain lost muscle mass in later life?
Yes, regaining lost muscle mass in later life is possible, but the earlier you start, the better the outcome. Resistance training is the cornerstone; adequate protein intake (approximately 1.2-1.6 g/kg/day) makes the effect somewhat greater.
When does your muscle strength start to decline?
Muscle strength reaches its peak somewhere between your thirties and forties and gradually declines after that. Regularly training your muscles with weights or resistance is the most effective way to slow that decline.
How quickly do I lose fitness if I stop exercising for a while?
A period of training protects your fitness for a while after you stop, but the older you are, the faster that effect fades. Start moving again as soon as possible to hold on to what you have built up.
