If 1RM, set, rep and hypertrophy leave you thinking that the world of working out and bodybuilding has developed its own language, there is help: This little ABC makes learning the most important workout and bodybuilding terms as easy as 123.
Anaerobic – The body’s generation of energy without the help of oxygen. The opposite is “aerobic” (“aer” is Latin for “air”). Weightlifting is mostly anaerobic, endurance activities like jogging are aerobic.
Barbell – a long handle where weights are put on and used with both hands at the same time. The smaller version is the dumbbell, which for most exercises is used with one hand.
Concentric – The portion in the movements of an exercise where you have to work against earth’s gravity, as in lifting a weight up. The opposite is “eccentric” – lowering the weight.
Definition – Visibility of the shape of muscles, mostly governed by how much body fat you have.
Exercise – A specific movement you do to train a muscle, as in “the barbell curl exercise” or “the push-up exercise”. Not to be confused with the verb, as in “I am exercising”.
Failure, to failure – Doing the movements of an exercise for as many repetitions as you can, “failure” standing for “muscle failure”.
Glutes – Short for “gluteus maximus”, the main muscles forming your behind.
