REPS
This is the number of repetitions of an exercise or technique you should aim to complete per set. One rep is th completion of an exercise from start to finish – for example, from the top position of a press–up to the bottom and up again. The number of reps you must do can be as low as one or as high as 50 depending on the session and your goals.
SETS
A set is a group of reps that you perform consecutively without resting or stopping. It’s usual to complete three sets of an exercise per session, but that can be lower or higher.
WEIGHT
As you’d expect, this is the amount of weight or resistance you use. It can simply be your bodyweight – and for this Marine programme it often is.
