I tried to make the time caps hard enough to where you get about 1-2min. of rest before the next session. Staying on pace will be tough for some and easier for others. So worst case scenario, just stop no matter where you’re at 1min. before the next section. That way you have enough gas in the tank to hit each piece hard. You’re also welcome to keep a slower effort and almost turn it into a 35min nonstop workout. It’s just not as fun that way 😉
