When I first took over as Fitness Director at Men’s Health, one of my central edicts was that I wanted to get rid of the idea of any ridiculous, time-frame-based fitness solutions.

Personally, I love a quick workout. I very rarely train for more than 30 to 40 minutes at a time, and commonly spend less than 20 minutes on any given workout. But the idea of 'seven-minute shreds', 'six-minute abs', 'five-minute legs' and so on? A big no-no from me.

That being said, as part of a larger programme the below workout – and the 21-15-9 CrossFit protocol in general – really can offer the prospect of real muscle, strength and engine building in as little as five minutes.

The only catch is that you have to work for it. Really, really hard.

Why Does It Work?

Once you reach the end of this workout, you will have accumulated 45 pull-ups, 45 dips and 45 squats.

If you’ve got access to a dumbbell, you could even perform the latter as goblet squats for additional load, bringing the stimulus more in line with the challenge you’re getting from the dips and pull-ups.

What to read next

Let’s break that down for a minute. Forty-five pull-ups? That’s more than the three sets of 10 you might have traditionally done in a standard workout. A fair amount more, in fact. It’s closer to five sets of 10 – a fairly decent volume. The same goes for the dips and squats.

Three moves at close to five sets of 10 each? Not a shabby workout.

And if you’re doing this for time (although you shouldn't sacrifice quality; keep those reps clean), it means you’ll most likely be chunking these sets up into small ‘microsets’, working incredibly close to failure in the process: a pivotal ingredient for muscle growth.

But as I say, if you want this workout to be quick, then, well, you have to do it quick. I’ve personally thrown this one in when I’m in a huge rush, and it’s over so quickly that the sweat doesn’t seem to catch up with you until afterwards.

The Workout

21, 15, 9 reps of:

Pull-Ups

Dips

Squats

Perform 21 reps of each movement, followed by 15 reps of each, followed by nine reps of each.

Break down the 21s, 15s and even the nines as necessary into smaller chunks, but complete all of the prescribed reps before moving on to the next.

Move quickly, but don’t sacrifice your form just to shave a few seconds from your time. The goal is fast, high-quality graft.

Record your finishing time, and next time, go faster. Aim to get it done in under five minutes.

The floor is yours.
