The subjects will attend for supervised training three sessions per week for 10 weeks (9-12). The strength training program involves dynamic contraction at intensities of 60 - 70 % of 1 repetition maximum (RM) to improve strength and muscle hypertrophy. Each session will contain 8 exercises on the major muscle groups. Each drill consists of 10-12 repetitions (reps) x 3 sets separated by one minute rest between sets.

High intensity interval training (HIT) three times per week. The three weekly supervised HIT sessions will include two 4x4 min interval sessions and one 10x1 min session. The HIT consist of "uphill" treadmill running/walking.

Based on the Norwegian recommendation we will encourage the control group to perform 60 minutes of physical activity at moderate to high intensity on a daily basis.
