This 30-minute-high intensity session will work your body, heart and lungs. You’ll be doing 30 seconds of work for three exercises, then 15 seconds’ active recovery before moving on to the next set of three exercises:

Part 1-squats, lunges with twists and press-ups, then star jumps, back extensions and sit-ups.

Part 2–high knees, twists and plank shoulder taps, then squats to knee raises, reverse lunges and star jumps.

Part 3–press ups, back extensions, sit-ups, then bicycle crunches, knee strikes and plank sprints.
