When can you exercise after weight loss surgery?
Vitalys gives a clear schedule. Straight after surgery light movement such as walking and cycling is allowed and helps prevent thrombosis. After two weeks you build up sport in small steps. After six weeks you may train with weights again, also building up gradually.
Swimming, baths and saunas wait until after two weeks, when the small wounds in the abdominal wall have closed. The lifting limit of 2.5 kilograms for the first four to six weeks lets the abdominal wall heal where the instruments went in.
Why strength training matters
When you lose weight fast, you lose not only fat but also muscle, and muscle determines a large part of your resting metabolism. That is why centres emphasise protein-rich food in the first months and building up strength training once it is allowed.
Exercise with less energy
People who exercised before surgery often notice lower energy in the first months, because they eat much less. Plan training around your meals, drink enough in small sips outside mealtimes and discuss with the physiotherapist or dietitian of your centre how to keep muscle mass while losing weight.
If you feel pain in the abdominal wall while exercising, stop and build up more slowly.

Staying active in the long term
Regular exercise helps keep weight off in the years after surgery. Choose activities you enjoy and can keep up, such as cycling, walking or swimming, and combine them with two strength sessions a week once you are fully recovered.
A simple twelve-week plan
Weeks one and two: walk several times a day, starting with ten minutes and building up. Weeks three to six: add cycling or swimming two to three times a week at a comfortable pace. From week six: add two short strength sessions a week with light weights or body weight, such as squats, wall push-ups and step-ups.
From week twelve most people can train normally again, as long as they eat enough protein and drink enough outside meals. Listen to your body: dizziness or unusual fatigue are signs to slow down and check with your team whether your food intake and blood values are in order.
Exercise and loose skin
Exercise improves muscle tone and overall fitness, but it cannot remove loose skin after major weight loss. Whether skin tightens depends mainly on age, genetics and how much weight you lose. If loose skin causes medical problems, discuss surgery with your team; it is not always reimbursed.
Exercise as an expat
Many Dutch gyms and sports clubs offer English-language classes, and cycling is an easy way to build activity into daily life in the Netherlands. Start gently and increase gradually, following the schedule of your centre.
Ask at the club whether a trainer has experience with clients after weight loss surgery, and mention your operation so exercises can be adjusted in the first months.
Protein and exercise
Exercise works best when you eat enough protein. Plan a protein-rich meal or snack within a few hours after training, drink enough water outside mealtimes and ask your dietitian whether your intake matches your activity level.
