02 TREADMILL SPRINT 3 SETS OF 25SEC

Once your heart rate has calmed down, get ready to jolt it into action again. Crank the treadmill to 10mph and set it to a 10% incline, standing off the belt (A). Lower yourself on using the handrails and sprint like Usain Bolt for 25 seconds (B).

Take a minute’s rest, then repeat twice.
