If you have little time to train but still want to make rapid progress, use supersets and dropsets.

SUPERSETS

In supersets, you do two different exercises directly or almost directly after each other, without rest.

Research among experienced strength athletes shows that supersets can save you 36% of time while achieving the same gains.

Please note: these are agonist-antagonist sets, where you train two opposing muscle groups one after the other, for example chest (push) and back (pull).

DROPSETS

With dropsets you lower the weight by 10 to 30 percent after a set and immediately do another set of repetitions, without rest. You do this a number of times.

Research shows that drop sets can reduce training time by 30-70% while still achieving substantial muscle growth.
