From 40 the body loses muscle every year unless someone objects. Why strength training is the most important training of the second half of life, what two sessions a week look like and how to start without injury.
In short
- Muscle is the largest metabolic organ: it stores sugar, lowers inflammation and protects against falls and fractures.
- Two sessions a week with six basic exercises are enough; three sets of eight to twelve reps close to fatigue.
- Progression counts: a little more weight or one more rep every two weeks.
- Protein at 1.4 to 1.6 grams per kilo, sleep and 48 hours of rest per muscle group turn training into muscle.
Why muscle decides old age
From the age of 40 the untrained body loses about one percent of muscle mass a year, from 60 twice as much. The result is called sarcopenia: less strength, slower metabolism, more belly fat, worse blood sugar, unstable joints, falls, fractures, dependence on care. Grip strength predicts mortality in large studies better than blood pressure. Muscle is also the largest metabolic organ: it takes sugar out of the blood, releases anti-inflammatory messengers and carries the basal metabolic rate. Whoever keeps it keeps almost everything else with it.
The plan: two sessions, six exercises
Full-body training twice a week, 40 to 50 minutes each, with at least one day of rest in between. Six movement patterns: squat, hip hinge like deadlift or hip thrust, horizontal push like bench press or push-ups, vertical push like shoulder press, pull like rows or pull-ups, and carry or core like farmer’s walk or plank. Three sets of eight to twelve reps each, with the last two being hard. That works with a barbell, dumbbells, machines, bands or body weight; what matters is the effort, not the equipment.
Progression: the difference between moving and training
Muscles grow only when the load increases. Every one to two weeks a little more weight, one more rep or a harder variant. Whoever starts squats with 20 kilos and moves 60 kilos a year later has built not only legs but bone, tendons and insulin sensitivity. A training log, even as a note on the phone, is the most important tool.
Starting safely
The first four weeks with light weights and clean technique, ideally with two or three sessions with a trainer or with good videos in front of a mirror. Pain in the joint is a stop, burning in the muscle is not. Warm up with five minutes of movement and light sets of the first exercise. Whoever has high blood pressure, heart problems or joint surgery talks to the doctor first; strength training is allowed and recommended with almost everything, but with an adjusted dose.
What turns training into muscle
Protein: 1.4 to 1.6 grams per kilo of body weight, spread over three to four meals, one of them in the hours after training. Sleep: in deep sleep the growth hormone that repairs is released. Rest: 48 hours per muscle group. Creatine, three to five grams daily, is the best-supported supplement for strength and muscle mass, also from 60. And patience: the first visible results take eight to twelve weeks, strength rises from week two.

Is strength training at home enough?
Yes, with dumbbells, bands or body weight, as long as the load increases. Push-ups, squats with a backpack, rows with a band and lunges cover the patterns. At some point it takes more weight.
Will strength training make me bulky?
Not without intent. Two sessions a week build muscle that makes the body firmer, not wider. Visible mass takes years, lots of volume and a calorie surplus.
Is strength or endurance training more important?
Both, in this order: whoever has time for only one takes strength from 40, because it vanishes fastest without training. Ideal are two strength and two to three endurance sessions.
