Guided Exercise Program for Severe Obesity Before Surgery

This trial is testing whether a structured exercise program—combining aerobic workouts and strength training guided by physical therapists—can help people with severe obesity build muscle, lose fat, and improve their overall health. The program uses both in-person sessions and remote monitoring through telehealth to make it easier for you to participate. Researchers want to see if this type of guided exercise could improve outcomes for people considering or preparing for weight loss surgery.

Severe obesity affects hundreds of thousands of people in Spain and causes serious health problems, but regular dieting and exercise alone often don't work well enough. While surgery can help, it can also lead to muscle loss and weight regain if people don't exercise afterward. This trial is trying to find out whether a guided, closely monitored exercise program—especially one delivered partly through telehealth—could help more people succeed by making exercise easier to stick with and more effective.
