The questions men past 30 actually ask about muscle, protein, recovery and training, answered from current research. Educational content only, not medical advice.

Yes, at any age. Untrained adults lose roughly 3 to 5% of their muscle per decade after 30, but resistance training reverses the trend at every age researchers have studied. The requirement doesn't change: hard sets, progression, protein, and sleep. The window never closes, it just stops forgiving neglect.
The research points to 1.6 to 2.2 grams per kilogram of body weight per day, roughly 0.7 to 1 gram per pound. The popular "1 gram per pound" rule sits at the top of that range: a simple, safe ceiling. Past 40, aim toward the higher end, because muscle responds a little less to each meal as you age. Spreading it across 3 to 4 feedings of 30 to 40 grams is a sensible optimization, but the daily total matters most.
2 to 3 hard sessions of 45 to 60 minutes covers most of the muscle growth on the table. Volume has diminishing returns: the jump from zero to around 10 hard sets per muscle per week buys most of the result. More can add a little, at a much steeper time cost.
No. Stopping 1 to 3 reps short of failure captures nearly all of the growth stimulus, with less joint stress and easier recovery. What matters is getting close on purpose, not grinding every set to collapse.
The big movements: presses, rows, pull-ups, squats and lunges. Bodyweight counts when you take sets close to failure. A doorway pull-up bar and a set of bands unlock most of it; adjustable dumbbells and a power tower cover 90% of what keeps you strong for life. One more edge from recent research: emphasize the stretched half of each rep, deep and controlled.
No. They are the last 10%, after food, training and sleep. A whey shake is a convenience for hitting your protein number, not a requirement. Nothing in a tub outworks a boring week of real meals and hard sets.
Both, with lifting as the non-negotiable. In a calorie deficit, resistance training preserves about 93.5% of the muscle you would otherwise lose dieting. Keep protein high, eat 250 to 500 calories under maintenance, and walk more: 8,000+ steps a day is the most underrated fat-loss tool there is.
Timing is the whole game. Cold water in the hours right after lifting can blunt the growth signal you just trained to create. Save the cold for rest days or wait at least 6 hours after training. The full breakdown is in the free Recovery Starter Kit.
For range of motion and moving well: solidly yes, the research is strong. For injury prevention: the evidence is mixed, and strength training itself is the better-proven protector. The genuinely exciting finding: training muscles at long lengths, deep stretched positions under load, appears to add growth. Stretch because it keeps you moving and training, not because of detox myths.
7 to 9 hours is where recovery research consistently lands. You don't need a perfect 8 every night, but chronic short sleep quietly taxes recovery, appetite and training quality. If you fix only one recovery habit, fix this one. It's free.
Both free guides go deeper: the training split, the staple meals, and the recovery routine that keeps you in the game.
