In an ideal world, many of us would like to hit the gym for an hour or two, with a decent warm-up, a well-thought-out workout and a gentle cool down. But life doesn’t always allow the time for that. In these circumstances we need something that’s quick and effective: enter the AMRAP workout. This speedy 12 minute session won’t just get your heart racing, but your muscles pumped too.

While you want to push yourself, you don’t want to go out too hard too fast, or you’ll blow out too quickly. The nice thing about this workout though is that the reps decrease with each exercise. Ready? Here’s your workout:
