Loose Skin on Your Thighs After a GLP-1
The short answer
Thighs are the area where the muscle underneath makes the most difference, because they hold the largest muscle groups you have — so there is more there to rebuild than anywhere else on you. That still does nothing to the skin itself: you cannot exercise skin, and squats change what sits under it. Inner thighs are usually the slower half, since that skin is thinner and has less beneath it than the front of your leg. And if a fold there is chafing, raw or sore, that is a question for your healthcare provider rather than a training problem.

Increased central adiposity
at or above 0.5 — the point NICE suggests keeping below
Why this one is useful if you lift. NICE states these classifications can be used for adults of both sexes and all ethnicities with a BMI under 35 — explicitly including adults with high muscle mass. That’s the gap BMI leaves: muscle inflates BMI, but it doesn’t inflate your waist.
A rough guide for planning, not medical advice or a diagnosis — NICE itself notes the ratio should be interpreted with caution because it isn’t a direct measure of central adiposity. Tape measurement also carries real error, so measure the same way each time and watch the trend rather than one reading. Anything about what this means for you belongs with your healthcare provider.
Arms and stomachs get all the coverage; thighs get almost none, even though they are where a lot of people first notice the change. Here is why legs behave differently, and what is actually yours to change.
Why thighs are their own case
Your thighs are load-bearing in a way your arms are not — they carried your body weight every day you walked, and the muscle in them is the biggest you own. That cuts both ways. There is more underneath a thigh to fill it out than anywhere else, which is why legs often look settled sooner than a stomach does; but there was also more volume there to lose, so the change can be dramatic.
The two halves of a thigh do not behave the same either. The front and outside sit over a lot of muscle and tend to look filled out as that muscle comes back. The inner thigh is the awkward one: the skin there is thinner, there is less under it to take up slack, and it rubs against its opposite number every time you walk. If your legs look fine from the front and not from the inside, that is the ordinary pattern rather than something going wrong.
What training changes here — and what it doesn’t
Be clear about the boundary first, because a lot of leg workouts are sold across it: no exercise changes skin. What lower-body training changes is the muscle under the skin, and on a thigh that is a bigger lever than almost anywhere else, simply because there is more muscle there to build.
It also matters which kind of training. In an eight-month randomised trial in sedentary adults with overweight or obesity, the aerobic and combined groups reduced fat mass the most, while the resistance and combined groups were the ones that increased lean body mass. Walking is doing real work for your legs and it is not doing that work — if the goal is the muscle underneath, the legs need loading, not just mileage. Is walking enough on a GLP-1 goes through that properly.
Lower-body work that is worth doing
Public-health guidance recommends muscle-strengthening activity that works all major muscle groups on 2 or more days a week, and for legs that is an easy box to tick without a gym. Sit-to-stands from a chair, step-back lunges, glute bridges, a standing hip hinge, and step-ups onto a low stair cover the quads, hamstrings and glutes between them.
Start with what you can control rather than what looks impressive — a chair squat done well beats a deep one done badly, and knees complain loudest when the pattern is wrong. The no-equipment workout has the full sequence, and the beginner home workout is where to start if none of this is familiar yet. Twice a week is the whole commitment.
The chafing problem is a separate problem
Inner-thigh skin that folds against itself traps moisture and rubs, and that is a skin-health issue rather than a cosmetic one. Skin that is sore, raw, rashy, broken or infected is a reason to see your healthcare provider — not something to train through, wait out, or treat with whatever the internet is selling this month.
The ordinary practicalities are worth having in place either way: longer shorts or a light legging under clothes, keeping the area dry, and not doing a hundred lunges on skin that is already raw. Swap to seated or single-leg work for a few days if rubbing is the limiting factor. The training will keep.
How to judge it fairly
Thighs look different sitting, standing, first thing in the morning, and after a long walk, and none of those views is the true one. Judged in a mirror on any given morning, a leg tells you almost nothing; judged in dated photos taken in the same light a season apart, it tells you quite a lot.
Give it months rather than weeks, and separate the two questions while you wait. Whether the skin will retract further is a matter of age, genetics and how fast the weight came off, which does loose skin tighten on its own covers; whether what you are looking at is skin at all is a different question, and is it loose skin or fat walks through it. The muscle is the only part of the three that answers to what you do this week.
Legs are the one area where the muscle underneath does the most visible work, and they are also the easiest place to train badly. Mira coaches every squat, lunge and bridge through your phone camera — scoring the form, counting the reps — so the twice-a-week habit that fills your frame back out is one you can actually keep.

Common questions
Do squats get rid of loose skin on your thighs?+
No — you cannot exercise skin, and no leg movement changes the tissue on top of your muscle. What squats and lunges do is build the muscle underneath, and because thighs hold the biggest muscle groups you have, that fill makes more visible difference there than on most of the body. It changes how the leg reads, not what the skin is doing.
Why do my inner thighs look worse than the rest of my legs?+
Because the inner thigh has thinner skin and less muscle beneath it to take up slack than the front or outside of your leg, and it rubs against the other leg constantly. It is the normal pattern after large weight loss rather than a sign you have trained wrong. Lower-body work still helps how the whole leg reads, just less dramatically on that inner surface.
Is walking enough for my legs on a GLP-1?+
Walking is genuinely good for you and it is not the same job as loading your legs. In an eight-month randomised trial, the resistance and combined groups were the ones that increased lean body mass, while aerobic work did the most for fat mass. Keep the walks and add two short strength sessions a week — they are answering different questions.
When should I see someone about loose skin on my thighs?+
If skin between your thighs is chafing, sore, raw, rashy or broken, raise it with your healthcare provider rather than waiting it out — that is a skin-health problem and it tends to get worse with friction, not better. For the appearance side, a dermatologist can tell you what is likely still to change, and skin removal surgery after a GLP-1 covers what that conversation involves.
