Repetition Maximum

Don't max out your weight training routine! Repetition maximum (rep max or RM) refers to the number of times you can do a given lift at a given weight with good weight training technique. 1 RM means you can do the lift once but not twice at that weight, such as a bench press 1 RM of 100 pounds. 3 RM means you can do the lift 3 times but not 4. Getting the max from your strength training workout sometimes means moderation.
