Shed those extra pounds with this high-intensity workout

FROM weight loss to reducing stress levels, many of us take to the gym to boost our health.
And now a new study from the University of Regensburg, Germany, has more to add: physical activity levels have an effect on the risk of some brain cancers and, more specifically, being overweight or obese significantly ups your risk.
High-intensity workouts using compound movements should be the weapon of choice, thanks to their fat burning abilities.
Keeping the exercise at a fast pace with little rest will create an afterburn effect, helping you to torch calories even after your workout is over, while using compound movements help to boost your metabolic rate.
Perform each exercise for the time allotted for your level without rest in between the moves.
Once one circuit is complete, take a minute’s rest then repeat.
Beginner: 3 x 30 seconds;
Intermediate: 4 x 45 seconds;
Advanced: 5 x 45 seconds
