This has been a unique week of training. Because there are basically multiple sets within each set, they require a lot of energy, planning, and time. While none of the phases in the Duel trainer will be easy, no other will keep you in the gym quite as long as this week.
None of that extra time in the gym has gone to waste, though. Partner dropsets provide benefits you can't get with less-taxing methods. You'll gain strength, because you're pushing your muscles and nervous system to move weight when they're tired. Dropsets also increase muscle size because the time your muscles are under tension (TUT) is vastly increased.
Don't hold anything back today! It's your last dropset workout, and you won't be back in the gym for a few more days.
