Strength training on a GLP-1: a programme that fits a tired, hungry body

The 30-second summary

• Two sessions a week of resistance training is the minimum effective dose for preserving muscle on a GLP-1.
• The right pattern is full-body, brief, and gentle in load: not bodybuilder-style training. Most women can do it at home with a single set of dumbbells and a wall.
• The point is the stimulus, not the intensity. Showing up matters more than how hard.

Why the bar is "two a week"

The literature on protein and resistance training in caloric deficit consistently shows that two sessions per week of resistance training, paired with adequate protein, preserves substantially more lean mass than diet plus cardio alone. (Cermak NM et al., AJCN 2012.)

Three sessions is better. Four sessions, for most women, hits diminishing returns and starts to interfere with recovery, especially when caloric intake is low. The sweet spot for women on a GLP-1 in active weight loss is two to three full-body sessions per week.

The opposite of this is the much more common pattern: long walks, light cardio, occasional yoga, none of which generates the muscle-loading signal the body responds to.

What the sessions actually look like

A working programme. Each session is 20 to 30 minutes. You do not need a gym.

Equipment

• One set of dumbbells. For most women starting out, a pair of 5 kg (10 lb) and a pair of 8 kg (15 lb) covers nearly everything for the first few months.
• A wall. (You will see why.)
• A clock or a phone timer.

That is it. A resistance band is a useful add-on if dumbbells feel like too much.

The session structure

Each session covers four movement patterns, in any order:

1. A squat. Bodyweight squats, then goblet squats holding a dumbbell at chest height.
2. A push. Push-ups against a wall, then on knees, then on the floor, whichever level lets you do 8–10 with good form.
3. A pull. Single-arm rows with one dumbbell, holding the other hand on a chair or a counter for support.
4. A hinge. Romanian deadlift with two dumbbells: a hip hinge that loads the hamstrings and glutes.

For each, do 2 to 3 sets of 8 to 10 repetitions. Rest 60 seconds between sets. Total time: 20 to 25 minutes.

That is the whole programme.

A more specific session, if you want one

Session A (Tuesday):

1. Goblet squat: 2 sets of 10
2. Wall push-up or knee push-up: 2 sets of 8
3. Single-arm dumbbell row: 2 sets of 10 each side
4. Romanian deadlift: 2 sets of 10
5. Plank: 2 holds of 20–30 seconds

Session B (Friday):

1. Reverse lunge with dumbbells: 2 sets of 8 each side
2. Overhead press with dumbbells: 2 sets of 8
3. Bent-over row with two dumbbells: 2 sets of 10
4. Glute bridge: 2 sets of 12
5. Side plank: 2 holds of 15 seconds each side

Rotate the sessions each week. The whole programme repeats indefinitely.

What progression looks like

For the first 4–6 weeks, focus on form, not weight. Watch a video of each exercise. Film yourself if you can. Movement quality is the foundation.

After 4–6 weeks:

• Add reps before adding weight. If 10 reps feels easy, do 12.
• Add weight when you can do 3 sets of 12 with good form. Move to the next dumbbell weight up.
• Add a third weekly session if you have the time and recovery. Not before.

Strength gains in the first 12 weeks are largely neurological, your nervous system learning the movement. Visible muscle changes take 12–24 weeks. The point in weeks 1–12 is showing up.

The two mistakes women on GLP-1s make

Mistake one: cardio without strength

Walking is great. Walking is also not the stimulus that retains muscle. A 10,000-step day with no resistance training, repeated for six months while losing weight, produces lean-mass loss that cardio cannot prevent.

Mistake two: trying to do too much

A four-day-a-week split programme aimed at a body-building physique is the wrong shape for a woman in caloric deficit. The fatigue, the under-recovery, and the under-eating compound. Two well-executed sessions a week, every week, for a year, produces vastly better outcomes than six weeks of four-a-week training followed by burnout and a six-month break.

What to do if you have not exercised in years

A reasonable on-ramp:

• Weeks 1–2: Walk 20 minutes a day. That is the entire programme. Do not add anything else.
• Weeks 3–4: Walk 20 minutes a day. Add one strength session per week, using only bodyweight (squats, wall push-ups, glute bridges). Two sets each, 8–10 reps.
• Weeks 5–6: Walk most days. Add a second strength session. Still bodyweight only.
• Week 7 onward: Two sessions a week, add dumbbells as available, follow the programme above.

You do not need to be "in shape" to start. You become in shape by starting.

Joint pain, back pain, fatigue

A few practical notes:

• Joint pain that comes on during exercise is a signal to reduce range or load, not stop. Pain that lingers afterwards for hours is a signal to see a physiotherapist.
• Back pain on Romanian deadlifts is almost always a form issue, usually the back is rounding instead of hinging at the hips. Watch a video, film yourself, or do them with a wall behind you to keep your spine neutral.
• Severe fatigue after sessions suggests under-eating or under-recovery. Eat more on training days, particularly more protein.

If a movement consistently hurts and the technique fix does not help within two sessions, swap it for something else. There is no exercise that is irreplaceable.

What Steady does with this

Steady's strength-training log is one tap from the activity card on the home screen. Logging two sessions a week shows up in the weekly scorecard alongside protein, water, and dose adherence, the four lines that protect muscle on a GLP-1.
