Strength Training 101: What to Do in the Gym

Read this before our call

"I don't know what I'm doing when I get in the gym."

That one shows up in my DMs constantly, usually followed by "so I just do the treadmill." Some women are doing Zumba five days a week and wondering where their muscle definition went. Others want to "tone up" but are scared lifting will make them bulky.

This guide gives you the basics, a plan you can start this week, and enough know-how to walk into the weights section like you belong there. Because you do.

Why lifting, and what "toning" means

"Toned" is just muscle you can see, with less fat covering it. So getting toned is two jobs: build some muscle, and lose some fat. Cardio helps with the second job. It barely touches the first.

Why this matters more after 40:

• You lose muscle with age, and faster around menopause. Lifting is how you keep it and build it back.
• More muscle helps your body handle carbs better and makes it easier to keep weight off.
• Lifting also supports your bones, which matters a lot as estrogen drops.
• Daily life gets easier: stairs, groceries, picking up grandkids.

And no, you won't get bulky by accident. Building muscle is slow, especially after 40. The women with big, visible muscle spent years trying very hard to get it. Two or three sessions a week gives you shape, not a bodybuilding trophy.

The movements and a simple plan

Nearly every good program is built on the same handful of movements:

A simple 2-day plan, doing each workout once a week:

• Day A: squat, push, pull, carry. 3 sets each.
• Day B: hinge, single leg, push, pull. 3 sets each.

Got 3 days? Rotate A, B, A, then B, A, B the next week. Each session takes 30 to 45 minutes. Start with a 5-minute warm-up: a brisk walk and a couple of light sets of your first exercise.

How heavy, how many reps

• Reps: 8 to 12 for most exercises, 10 to 15 for the small ones.
• Weight: heavy enough that the last 2 reps are hard but your form still holds. If you could have done 6 more, it's too light. That's the most common mistake I see. Pink 3-pound dumbbells for 30 reps is cardio wearing a disguise.
• Rest: 60 to 90 seconds between sets.
• Progress: write down your weights. When you hit the top of the rep range on every set, go up a little in weight next time. That steady increase is what actually builds muscle.
• Form first: slow and controlled, full range you can do without pain. If you're not sure, record yourself on your phone, or book a session with a trainer to check your technique.

Getting sore in the first couple of weeks is normal. Being so sore you can't move means you did too much. Hold back on volume, not effort.

Sore knees, a bad back, or nerves about the gym

If something hurts, there's almost always a version you can do. Bad knees: try box squats to a bench, hip thrusts, and step-ups at a lower height. Bad back: try supported rows, glute bridges, and goblet squats instead of barbell lifts. Sharp pain means stop. A dull ache from effort is normal. Anything ongoing, or an injury or surgery that's still recent, should be cleared with your doctor or physio first.

Nervous about the gym? Go at quieter times, have your workout written on your phone, and start with machines and dumbbells. Nobody's watching you. They're looking at themselves in the mirror.

Working out at home? A pair of adjustable dumbbells or a couple of resistance bands covers the whole plan above.

Your 7-day checklist

• Do Day A once and Day B once this week.
• Write down every exercise, weight and rep.
• Find the weight where the last 2 reps feel hard.
• Note anything that hurt, and where.
