Harvard Health is direct that you are never too old to benefit from strength and power training, and NIA-supported research shows many older adults can increase muscle strength with exercise. The response blunts with age, but it never disappears.</div></details><details><summary>How much protein do I actually need?</summary><div class="acv-a">The baseline RDA is 0.8 grams per kilogram of body weight per day. If you are strength training and trying to defend or build muscle, research supports 1 to 1.2 grams per kilogram. For a 90 kilogram man, that is roughly 90 to 108 grams a day.</div></details><details><summary>Do pushups and squats count, or do I need weights?</summary><div class="acv-a">They count. Body-weight exercises like pushups and squats, resistance bands, medicine balls, machines and free weights are all legitimate resistance training. What matters is working the major muscle groups to the point where another repetition would be hard.</div></details><details><summary>What is sarcopenia, and should I worry about it?</summary><div class="acv-a">Sarcopenia is the age-related decline in muscle mass, strength and function. It affects about 5 to 13 percent of people ages 60 to 70 and up to half of people over 80, and it raises the risk of falls and fractures. Strength training and adequate protein are the main defenses. If you feel general weakness, mention it to your doctor.</div></details><details><summary>Is walking enough exercise on its own?</summary><div class="acv-a">Walking is essential but not sufficient. NIA-supported researchers found the best recipe for protecting physical function is walking plus resistance training together. Keep the walks, and add two lifting days.</div></details><details><summary>How fast will I see results?</summary><div class="acv-a">Strength gains from a consistent 2-day-a-week program build over weeks to months. The molecular signals from each session linger for hours and build a cumulative effect, and even a low-intensity strength and walking program has substantial benefits.</div></details></div><div class="acv-secondary">Wondering where you stand overall? <a href="/#assessment">Take the free 5-minute Healthspan Snapshot</a> and see your strongest and weakest of six dimensions.</div></div></div>
