Strength Training for Beginner Women: Lifting, Food and the Scale

Lifting on its own doesn't take off much fat. A 2022 review of strength training studies found it lowered body fat by about 1.5 percentage points on average, compared with doing no exercise. The effect didn't differ between women and men. That's real, but it's small. Eating a bit less is what takes most of the fat off.

Eating less on its own has a catch. A 2026 review of 34 trials in people with overweight or obesity found that cutting calories took off lean mass (particularly muscle) along with the fat. People who also exercised kept nearly half of the lean mass that dieting alone took. Adding strength training kept about 0.8 kg (almost 2 pounds) more than diet alone.

So each piece has a job:

• Food: eat a little less, mostly real food, and no crash diets. Strong, not starving.
• Lifting: hold on to your lean mass, and get stronger while the fat comes off.
• Walking: the easy cardio. It fits around everything else.
• Protein: backs up the lifting. The International Society of Sports Nutrition puts it at 1.4 to 2.0 grams per kilogram of body weight a day for most people who exercise. That's about 0.6 to 0.9 grams per pound.

Don't over-think the protein, though. A 2018 analysis of protein supplement studies found that the training itself drove much more of the gains in muscle mass and strength than the extra protein did. Showing up to lift is the part that counts.

In your first few weeks, you'll get stronger fast. Most of that early jump isn't new muscle yet. It's your nervous system learning the moves. In one small study, most of the strength people gained at first came from the nervous system, and muscle growth took over after about three to five weeks. A later review adds that muscle starts growing from the start too. It just takes longer to show.

Your body changes more slowly. Fat comes off a little at a time, and if you're also keeping lean mass, the scale moves less than the work you're doing. A week where your weights went up and the scale didn't is a normal week.

Soreness runs on its own clock too. Muscle soreness from a new move usually peaks 48 to 72 hours later, and it eases as you keep doing the same moves. Week 1 is usually the sore one, and the stairs may take it personally. Our 6-week plan says what's normal and what to stop for.

Keep track of three things:

1. The weight and reps for every move, every session. Write them in your phone's notes, or in the app if you're doing a challenge. This is the one that moves first.
2. How your clothes fit. Pick one pair of jeans and try them on once a week.
3. How many sessions you did, out of how many you planned. In month one, this is the one we'd watch most. Get this one right and the first one takes care of itself.

Frances, new to lifting in one of Cheryl Coulombe's challenges, wrote: "I love the simplicity of entering my reps in the app. The satisfaction of seeing my lift totals are motivating."

How heavy to start

Some online charts give every woman the same pound range for each move. Your first session gives you yours. Pick a weight you could lift two or three more times when you stop the set. The American College of Sports Medicine says stopping a few reps short of failure (the point where you can't do another rep) is enough. Our guide for women over 50 shows how to find your weight, and it works at any age. When the last reps stop feeling hard, go up.

Annie, a novice at weights with only a few items at home, wrote that "when I need bigger weights that will be an occasion to celebrate!"

The US guidelines ask adults to do muscle-strengthening work for all major muscle groups on 2 or more days a week. That's the minimum. We'd start at three: three short full-body workouts a week, about 30 minutes each, with walks on the days in between. Our 6-week plan is exactly that: two workouts, A and B, that you take turns doing, three days a week, at home or in a gym. Start with weeks 1 and 2, which are for learning the moves. If you have a health condition, check with your doctor before you start.

The plan is the easy part. Still showing up in week 4 is the hard part, and that's where other people help. Of 93 winners we interviewed, 90% credited the challenge community for motivation and support.

Worried you're too new for this? Monica, a newer lifter, wrote about her challenge: "It’s not intimidating at all, which was important for me, as a newer lifter. I feel stronger than I’ve ever been." And Mia, on her very first workout program: "What I love most is that I didn’t need to be “in shape” before starting."

Six weeks is long enough to feel the difference and short enough to finish. Walk, lift weights, eat real food. Then see how you feel.
