The resistance training will include bodyweight functional exercises and resistance exercises using elastic bands. The intensity of resistance exercise will progressively increase according to levels of progressive length and resistance of the elastic bands. The volume of resistance training will start with one set of 8 repetions. It will then gradually increase alongside the program to 2 sets of 12 repetitions. Participants will also be guided to assess their subjective effort using the Borg scale (RPE 12-15).
