An ascending ladder will increase the number of repetitions each round by a specified multiple.

For example, Squats and Burpees ascending in multiples of 2 up to 10 (sometimes listed as 2/4/6/8/10) will go as follows.

Round 1 - 2 Squats, 2 Burpees.

Round 2 - 4 Squats, 4 Burpees.

Round 3 - 6 Squats, 6 Burpees.

Heres an example of a 1/2/3/4/5 ladder of Squats and Burpees in action!

and so on.

A descending ladder is the same, but the reps will decrease each round.
