Arms & Interventions
High-intensity resistance training
Full body, progressive strength training with Theraband® Elastic bands. Three times per week for 12 weeks - 3 weeks with supervised sessions at the clinic, and 9 weeks of home training. Three guided sessions will be offered during the home training period.
Intervention: High-intensity resistance training (Behavioral)

Intervention: Multidisciplinary rehabilitation program (Behavioral)
General physical activity
12 weeks of general physical activity - 3 weeks with supervised sessions at the clinic, and 9 weeks of individually adjusted home training. This include circle-training, low-intensity resistance exercises, endurance exercises, ball playing, body awareness, stretching, and relaxation techniques, and similar activities. Neither moderate nor high-intensity resistance exercise is included for participants in this group.Three guided sessions will be offered during the home training period.
