Looking at this workout the main thing I would change is the length of the AMRAP. For a couplet workout with an ascending ladder rep scheme I usually don’t go over the 7-8 minute mark, especially with low intensity movements that can be performed at higher velocities. Much beyond that time the reps for each movement would get too high and the athlete would have to start breaking them up more, eliminating the cardiovascular effect that is intended.
If you go beyond the 8ish Min mark on ascending ladder rep scheme workout I recommend either using three to four movements or heavier/more complex movements. If you choose to use 3-4 movements then they will still be a large cardiovascular effect because reps will not get to high. On the other hand, if you choose to use heavier or more complex movements then the adaptation you get will be based off the movement that is the limiting factor, wether it is skill or strength based.
