What exercise should you do on GLP-1 medication?
On a GLP-1 medication, the exercise that matters most is strength training 2–3 times a week, because it is the best tool you have to keep muscle while you lose weight. Add walking or other easy cardio on most days, building toward the US guideline of 150 minutes a week, and a few minutes of balance work if you're over 50. Start small, keep it low-impact, and fit it around how you feel after your dose.
Below: what each kind of exercise does for you on the medication, the order to add them in, a weekly plan for three starting levels, what to pick for bad knees, low energy, 60+ or diabetes, how hard to work, and a 4-week start.
Why exercise matters more on a GLP-1
- Muscle. Some of the weight lost on these medications is lean mass, not fat. In the STEP 1 body-scan substudy, lean mass made up roughly two-fifths of the weight lost on semaglutide. Strength training is the main way to protect it. Our guide on how to prevent muscle loss on GLP-1 goes through the trials.
- Fat loss. In a 2021 NEJM trial (Lundgren and colleagues), adults who combined liraglutide with exercise lost about twice as much body fat percentage as those on either one alone, and kept more of the health gains.
- Bone. Losing weight can lower bone density. Weight-bearing exercise (walking, stairs, lifting) loads the bones and helps keep them strong.
- After stopping. A Danish trial (Jensen, 2024) found people who had exercised regained less weight in the year after stopping liraglutide than those who had only taken the drug.
A 2025 joint advisory from four US obesity and nutrition societies on supporting GLP-1 therapy names regular physical activity, including resistance training, alongside protein, as a priority for people on these drugs.
The types of exercise, and what each does for you
| Type | Examples | What it does on a GLP-1 | How much |
|---|---|---|---|
| Strength (resistance) | Sit-to-stands, wall or counter push-ups, rows with a band, dumbbells, machines | Keeps muscle and strength; loads bone | 2–3 days a week, all major muscle groups |
| Moderate cardio | Brisk walking, cycling, swimming, water aerobics, elliptical | Heart and lung fitness, blood sugar, mood, more calories burned | Build toward 150–300 minutes a week |
| Everyday movement | Steps, stairs, standing breaks, housework, gardening | Adds up; keeps you from long sitting spells | Most of the day; break up long sitting |
| Balance | Standing on one foot, heel-to-toe walk, tai chi | Fewer falls, steadier walking | A few minutes, 2–3 days a week if you're over 50 or unsteady |
| Flexibility | Gentle stretches, yoga | Easier movement; nice after a workout | Optional, a few minutes |
The amounts come from the US Physical Activity Guidelines for Americans (2nd edition), which apply to adults whatever their weight or medication.
Which to start first
If you can only do one thing, make it strength training. If you can do two, add walking. Here's the order we'd build in:
- Two short strength sessions a week. 20–30 minutes, six to eight moves, whole body. This protects the thing the medication puts most at risk.
- A daily walk. Start with 10 minutes, after a meal if that sits well with your stomach.
- A third strength session, or longer sessions, once two feel routine.
- More cardio minutes, working toward 150 a week.
- Balance work, tucked into the end of a strength session.
Our guide to strength training on GLP-1 has the two workouts, for home, dumbbells or a gym, with sets, reps and when to go heavier.
A weekly plan for where you are now
| Day | Starting from nothing | Some exercise already | Already active |
|---|---|---|---|
| Mon | Strength A, 20 min | Strength A, 30 min | Strength A, 40 min |
| Tue | Walk 10 min | Walk 25 min | Cardio 30–40 min |
| Wed | Walk 10 min | Walk 20 min + balance 5 min | Strength B, 40 min |
| Thu | Strength B, 20 min | Strength B, 30 min | Cardio 30 min, some brisk intervals |
| Fri | Walk 10 min | Walk 25 min | Strength A, 40 min |
| Sat | Walk 15 min | Strength A, 30 min, or a long walk | Long walk, hike or ride, 60 min |
| Sun | Rest or a stroll | Rest or a stroll | Rest or easy |
| Week total | 2 strength, about 55 min walking | 2–3 strength, about 90–115 min cardio | 3 strength, 150+ min cardio |
Move the days around your dose. Many people feel worst in the 1–2 days after their weekly shot: put walks there and strength on the days you feel best. Cleveland Clinic suggests starting gently in the first weeks and after each dose increase. Move up a column once your current one feels routine for 3–4 weeks.
What to pick for your situation
| If you… | Do this | Go easy on |
|---|---|---|
| Have sore knees or hips | Cycling, swimming, water walking, sit-to-stands from a higher chair, glute bridges, step-ups on a low step | Running, jumping, deep lunges; see a physiotherapist for pain that lasts |
| Feel low on energy or sick after your dose | Short walks, seated strength moves, 10 minutes is enough that day | Long or hard sessions, exercise on an empty stomach |
| Are 60 or older | Strength 2–3 days, balance 2–3 days, walking; a chair or counter for support | Fast changes of direction until balance is good |
| Have type 2 diabetes on insulin or a sulfonylurea | Any of the above, with your glucose checked before and after as your care team advises | Long sessions without a snack nearby; see the safety section |
| Are in a larger body and new to exercise | Water exercise, cycling, walking in short bouts, wall push-ups, chair work | Floor work that is hard to get up from, high impact |
| Don't like gyms | A home routine with bodyweight and one set of dumbbells or bands | Nothing: home training works for muscle |
| Already run or play a sport | Keep it, add 2 strength sessions, eat enough protein | Big jumps in mileage while eating very little |
How hard should exercise feel?
- Cardio: the talk test. At moderate intensity, the CDC's rule is that you can talk but not sing. If you can sing, speed up a little; if you can't speak in sentences, slow down.
- Strength: 2–3 reps in reserve. End each set when you could do 2 or 3 more good reps. The last few should feel hard but steady, never sloppy. When 12 reps feel easy, make it a little harder.
- Hard intervals (fast cycling, jogging bursts) are fine once you have a base and feel well, but not in your first month or the days after a dose increase.
Is walking enough on its own?
Walking is a great base and the easiest thing to keep, but on its own it doesn't load your muscles enough to protect them while you lose weight. Pair it with strength work. For a step goal, a 2022 Lancet Public Health analysis (Paluch and colleagues) found the lowest risk of death at about 6,000–8,000 steps a day for adults 60 and over and 8,000–10,000 for younger adults. Count steps if it helps; minutes of brisk walking matter more than the exact number.
Cardio options compared
| Activity | Joints | Good for | Watch out for |
|---|---|---|---|
| Brisk walking | Low impact | Everyone; free; loads bone | Shoes with support; heat |
| Cycling (bike or stationary) | Very low | Bad knees, larger bodies | Seat height; doesn't load bone much |
| Swimming and water exercise | Very low | Joint pain, heat, larger bodies | Doesn't load bone; needs a pool |
| Elliptical | Low | Gym users; a step up from walking | Easy to coast; use the talk test |
| Rowing machine | Low | Whole body, some strength | Learn the form; back |
| Jogging and running | High impact | Fit, pain-free people who like it | Start with walk-jog bouts |
| Dance or group classes | Varies | People who keep going when it's fun and social | Jumping moves; pick low-impact versions |
Your first 4 weeks
- Week 1: two 15–20 minute strength sessions, 1 set of each move. Walk 10 minutes on 3 other days.
- Week 2: 2 sets of each move. Walks to 10–15 minutes, 4 days.
- Week 3: 2–3 sets. Add 5 minutes of balance after one session. Walks to 15–20 minutes.
- Week 4: try a third strength session or a longer weekend walk. Write down a 30-second chair stand count and compare it with week 1.
Don't add more than one thing per week. If a week goes badly (side effects, travel, a dose increase), repeat it rather than skipping ahead.
Food and water around exercise
- Eat something first if your last meal was more than 3–4 hours ago: a yogurt, a banana, a glass of milk. Training on an empty stomach while eating very little is a common reason for dizziness.
- Protein after strength work, with your next meal or a snack: 20–30 g. Our guide on how much protein on GLP-1 works out your daily number.
- Water. These medications can make you drink less, because you feel full. Sip through the day and before and after exercise, more in the heat. Pale yellow urine is a simple check.
Safety: who should check first, and when to stop
Most adults can start walking and light strength work without a check-up. Talk to your doctor first if you have heart disease, chest pain, fainting spells, uncontrolled blood pressure, diabetes with nerve or eye problems, or a recent injury or surgery.
- Low blood sugar. GLP-1 medications on their own rarely cause it, but with insulin or a sulfonylurea the risk rises with exercise. Know the signs (shaking, sweating, confusion, a pounding heart), carry fast sugar, and follow your care team's plan.
- Stop and get help for chest pain or pressure, fainting or near-fainting, sudden breathlessness that doesn't settle, or severe belly pain.
- Skip the session if you're vomiting or can't keep fluids down. Rest and drink; call your prescriber if it goes on.
If you've lost muscle already, our guide on symptoms of muscle loss on GLP-1 has four simple home tests to track it.
Common mistakes
- Only doing cardio. It helps your heart, but strength work is what keeps muscle.
- Starting too hard. A first week that leaves you sore for days is a common reason people stop.
- Training on almost no food. Dizzy, weak sessions don't build anything.
- Waiting to feel ready. Ten minutes on a low day counts.
- Never making it harder. The same light weights for months stop working; add a rep, a set or a little weight.
- Ignoring the dose schedule. Plan hard sessions for your good days.
Questions people ask
What is the best exercise on GLP-1?
Strength training, because it protects muscle during weight loss. Pair it with walking or other cardio you enjoy enough to keep doing.
Do I have to exercise on a GLP-1?
The medication works without it, and its label pairs it with reduced calories and more activity. Exercise is what protects muscle, fitness and bone, and the trials suggest it helps keep weight off later.
How many days a week should I exercise?
Some movement most days, strength on 2–3 of them, and at least one easy or rest day. Start with fewer and build.
Can I do HIIT or run on Ozempic, Wegovy or Zepbound?
If you're already fit and feel well, yes. Build up to it, eat beforehand, and avoid it in the days after a dose increase.
When is the best time of day to exercise?
The time you'll keep. Many people find 1–2 hours after a light meal sits best with their stomach. There's no proven best hour relative to your shot.
Can I build muscle on a GLP-1?
Beginners often gain strength even while losing weight, if they train and eat enough protein. Keeping the muscle you have is the main goal.
Pair your training with the right protein
Exercise keeps muscle only with enough protein behind it. The free 2-minute check gives your daily target in grams and what to work on first.
