Low Intensity Blood Flow Restriction Training Study

Session 1 - baseline testing * 5-minute warm-up; 1RM calculation for both right and left legs using a supine leg press machine; isometric quadriceps strength measurement using a dynamometer; muscle thickness measurements of both right and left quadriceps muscle using ultrasound technology. * After day 1 testing; randomly allocate subjects to either control group or experimental group Sessions 2-13 - 6 weeks of exercise protocol, 2x/per week Both the experimental and control groups will complete the same protocol for the entirety of the study: * 5- minute warm up * Using a single-leg press exercise machine: Subjects complete the testing protocol with either partial blood flow restriction (cuff inflated to 100-250 mmhg depending on size of person) or no blood flow restriction (placebo inflation) on right limb. * Protocol: 30 repetitions - 15 repetitions - 15 repetitions - 15 repetitions with each set separated by \~30-90 seconds. * Right and left legs will be alternating, but only one leg will have the occlusion cuff Session 14 - Re-test \- Re-check 1RM, isometric quad strength, as well as muscle thickness of quadriceps with ultrasound
