The exercises below cover most of what a first year needs. A trainer teaches them in the first few sessions, then loads them progressively.
How to squat properly
Stand with feet about shoulder-width apart and toes turned slightly out. Brace your stomach as if about to be prodded, then sit down and back between your heels, keeping your chest up and your knees tracking over your toes. Go as deep as you can while your back stays in the same position, then drive up through the whole foot. Start with a goblet squat, holding a dumbbell at your chest, before a barbell goes on your back.
How to deadlift
Stand with the bar over the middle of your feet. Hinge at the hips and bend your knees until your hands reach the bar just outside your legs. Brace, pull your shoulders back slightly so your back is flat, then push the floor away and stand tall, keeping the bar close to your legs. Lower it the same way. A Romanian deadlift from a standing start is the usual first version, because it teaches the hinge without the setup.
Hip thrusts
Sit with your upper back against a bench and a weight across your hips, feet flat and about hip-width apart. Drive through your heels to lift your hips until your body is straight from shoulders to knees, squeeze at the top, and lower under control. The hip thrust loads the glutes heavily with little strain on the lower back, which is why it appears in so many programmes. A pad under the bar makes it comfortable.
A dumbbell workout for women
Dumbbells suit a crowded gym floor and a first block: a goblet squat, a single-arm row, a dumbbell bench press, a Romanian deadlift and a farmer's carry make a complete session. Each side works on its own, so a weaker side cannot hide behind a stronger one. Choose weights you can lift for 8 to 10 clean repetitions, and move up when 3 sets of 10 feel steady.
