Grab a bar for an intense whole-body muscle-building circuit.

By Jon Lipsey

If you think using a barbell without any weight means this workout is going to be easy, you’re in for a shock. This session is designed to be performed as a circuit, so you don’t take any rest between moves. This will really challenge your energy levels and if you’re doing the advanced version of the routine you’ll be banging out 20 reps with 20kg for several moves in a row.

The good news is that the workout only lasts 15 minutes. Even better, the intensity of the session means you’ll carry on burning calories long after you’ve stopped exercising, because your body will use a lot of energy to get you back to equilibrium.
