A repetition in weight training would be more than one lifting motion.
If I was doing 8 repetitions (aka reps) on squat, I would squat with the bar 8 times. Usually you do so many sets with a set amount of repetitions.
RM stands for repetition maximum. For example, a 1RM for the squat would consist of the maximum amount of weight that one could squat for 1 rep (repetition). A 5RM squat would be the maximum amount of weight one could squat for 5 reps.
repetition
W1RM in strength training means "working 1 repetition max."
High repetition training at lower intensities is generally not as effective for muscular hypertrophy compared to moderate to high intensity training. Hypertrophy is typically best achieved with a combination of moderate weight and moderate to high repetitions, with a focus on progressive overload over time. Training at 55 to 65 percent of 1RM may not provide enough stimulus to maximize muscle growth.
No. High weight, Low repetition.
Economical training means training in repetition various technical and tactical topics while the pace remains elevated to improve conditioning.
Repetition, rehearsal, exercise, preparation, training, run-through, and drill.
Repetition is the act of repeating or doing something multiple times. In writing or speaking, repetition can be used to emphasize a point or create a rhythm. In fitness or training, repetition refers to performing the same exercise or movement multiple times in a row.
