Concurrent Training: Combining Strength & Endurance Exercise link

Concurrent training is the inclusion of both resistance and endurance training within the same training program. For example, if you are a runner who repeats the pattern of running 6-7 days a week while also weight training 2-3 days/week; you are training concurrently. While this type of training is advantageous for improving body composition compared to endurance or weight training alone; concurrent training does not produce as great of an increase in muscle mass or strength as weight training alone.
