You do not need a barbell, an app subscription, or a perfect plan to start strength training. You need a few basic movements, light or no weight at first, and twelve weeks of steady practice. Here is what those weeks are for, and how to move through them.
Strength training, also called weight training or resistance training, is exercise designed to improve physical strength. Per Wikipedia's overview, it can involve lifting weights, bodyweight exercises such as push-ups and squats, isometric holds like planks, and explosive plyometric moves. Early on, much of the progress is not muscle at all. Beginners are training the signals between brain and muscle, which is why the first weeks feel like learning a skill.
Weeks one to four: learn the movements
The first month is for pattern, not load. Pick simple moves: squats, push-ups, planks, and rows if you have a band or a light weight. Each performance of a movement is a repetition, and two or more repetitions make a set, with rest between sets. Move with control, and stop well before your form breaks. Good form means using the muscles the move intends, not swinging the load elsewhere. Per the overview, improper form can lead to strains and fractures. A simple pattern works: about ten repetitions, a rest of roughly two minutes, and a few rounds.
Weeks five to eight: add a little load
Strength training runs on progressive overload. Muscles are subjected to gradually increasing resistance over time to stimulate adaptation and growth, per the same source. In practice, this is the month to make exercises slightly harder. Add weight, slow the movement down, or try a tougher variation. The muscles respond by growing larger and stronger. Keep the jumps small. The aim is gentle challenge, not strain.
Weeks nine to twelve: protect recovery
By now the sessions feel familiar, and the temptation is to add more and more. Resist it. Recovery between training sessions is fundamental to strength training, per the overview. When the body cannot recover, performance drops and the chance of injury climbs. Leave rest days between hard sessions, and treat lingering soreness as information. A warm-up still earns its place. The National Strength and Conditioning Association strongly recommends warming up, though evidence that warm-ups reduce injuries during strength training is limited, per the same source. This connects to our earlier piece, Strength training after 40: a realistic place to start.
What twelve weeks can give you
The list of gains is longer than most beginners expect. Strength training can increase muscle, tendon, and ligament strength, bone density, and metabolism. It can improve joint and cardiac function, and it can reduce the risk of injury, per the overview. It also fits inside a bigger picture. About 150 minutes of moderate-intensity exercise per week is the usual benchmark for reducing health risks, per Wikipedia's exercise overview, and strength work slots neatly into that frame.
A note on pain
Soreness after a new workout is common. Sharp pain, joint pain, or pain that lingers is different. Stop the movement that causes it, and ask a professional to look at it before you load it again. The same rule applies to illness: a sick body does not need a workout on top of it. Beginners who rush their loads pay for it. The overview's warning about strains and fractures is not decoration.

Conclusion: Twelve weeks from now
Twelve weeks is long enough to change what your body can do, and short enough to actually finish. Learn the movements first, add load slowly, and guard your recovery. Do that, and by the final week the habit will be pulling you forward on its own.
