1. Weight Training Terms Muscular Strength – The ability of the muscle to exert maximal force against a resistance. Muscular Endurance – The ability of the muscle to contract repeatedly, with a submaximal force. Repetition Maximum – the most weight lifted for a given number of repetitions, used to measure muscular strength. Written as 1RM, referred to as your “max.”  Load – the amount of weight lifted. Always a percentage of 1RM.  Repetition – The number of times a given exercise is performed.  Set – A completed number of repetitions performed consecutively without resting.

2.  Overload – Placing greater stress on the body than what it is accustomed to.  Specificity – Selecting particular exercises or training methods to match particular outcomes desired.  Slow Twitch Fibers – red muscle fibers, developed with aerobic exercise. Low to moderate intensity, long in duration. Fast Twitch Fibers – white muscle fibers, developed with anaerobic exercise. High intensity, explosive exercises, short in endurance.  Hypertrophy – The enlargement of the muscle.  Atrophy – Decrease in the size of the muscle.  Ergogenic Aid – Performance enhancing supplement or drug
