Training Lingo 101

Knockout Training Club Member doing the TRXHere's the 411 on all the lingo we use for our training programs:


Reps is an abbreviation for repetitions. This is the number of times that you perform a given exercise. (i.e. if you do 10 squats in a row, you did 10 reps of squats)


Sets are the number of times that you perform a given number of reps for an exercise. (i.e if you do 10 squats, rest, and repeat that 3 times, you did 3 sets of 10 reps)

Super sets

Super sets when two exercises are performed for a given number of reps each with little to no rest in-between and then repeated for the given number of sets. (i.e. I perform 10 reps of squat and then immediately follow that with 10 reps of push-ups and then rest)

Rate of Perceived Exertion (RPE)

RPE is a 1-10 rating scale used to evaluate the intensity of a lift or exercise. A 1 means “I can do it all day” and a 10 means “I can maybe do it once.” More of the RPE scale here.


Finisher is a term used to describe the end of a typical class when we focus on metabolic conditioning (or what some might consider "cardio"). The intensity is usually higher and rest interval shorter than the work performed in the middle of a class.  Finishers are the sweaty fun part of class that last anywhere from 5-10 minutes.


Complexes are a string of exercises performed back to back in order without stopping.  These are typically performed with one kettlebell or dumbbell with the purpose of metabolic conditioning. (i.e. using 1 kettlebell I do 10 x 2 handed swings, then 10 squats, then 10 goblet cleans, then 10 more 2 handed swings without ever putting the kettlebell down, once all drills are complete I rest)


An interval is a time-based or repetition-based training format. (i.e. I do squats for 30 seconds with a 15 second rest, a 2:1 ratio)
