Gym
All gym sessions were supervised by two physiotherapists for the initial 6 months. The aim of the first four visits (weeks) to the gym was to familiarize study subjects with the safe and appropriate use of the weight training equipment. No free weights were used. The training prioritized postural muscle groups of legs (quadriceps/hamstring), back (lower/upper) and trunk, with additional workouts for the chest and arms. Starting weights were based on the participant’s results of a 4-week tutorial and prediction of one repetition maximum (1RM) (Borg’s scale) [
