You’ll see that your workouts are often written out in supersets, which are when the exercises are “chained” together so rather than do 3 sets of 1 exercise before moving to the next, you do 1 set of each exercise in the chain before returning to the start of that superset.
These can also be known as couplets when there are 2 exercises; triplets when there are 3 etc; typically I’ll call them rounds there are 4 or more exercises in a chain.
When you do a superset, you perform 1 set of each exercise as listed according to the number and letter, then return to the beginning for set 2 of that super set. For example:
1a: Squat: 3×5
1b: Push-up: 3×5
2a. Swing: 3×10
2b. Single Arm Row: 3×10 each side
In this example, you perform 1a then 1b with as much or little rest as you need, then rest after 1b before returning for a second run-through of those 2 exercises. Once all 3 sets/rounds are done, you move on to 2a and 2b.
Sometimes there are more than 2 exercises in a superset.
“Traditional” Sets look like a number without a letter, like this:
- Squat: 3×5
- Push-Up: 3×5
