This arm is a long-term, Social Cognitive Theory (SCT)-based intervention, emphasizing self-regulation and other SCT strategies to optimize training, with faded contact.
Behavioral: SCT-based Resistance Training exercise program
Two supervised RT sessions per week for the first 3 months, then a self-monitored RT phase for the remainder of the study, with primarily Internet-based contact.
Active Comparator: Control
This arm will be the "control" condition; a Standard intervention with minimal contact.
Other: Standard Intervention with minimal contact
This is the control condition for comparison; the approach will be identical to the experimental condition, but without the theoretical components (skills to increase self efficacy for RT, self regulation for RT). Contact with the study staff will be reduced from that received by the experimental group.
