What is it?
‘Peripheral heart action (PHA) workouts operate by switching from an upper-body exercise to a lower-body exercise and then back again,’ says Mark Roberts, director of Personal Space gym. ‘They use your heart to maintain a high intensity that will burn fat and build muscle at the same time.’
What should I do?
Choose two upper-body and two lower-body exercises. Then do 12 reps per exercise, alternating between your upper and lower body with 30 seconds’ rest in between. Rest for 90 seconds between circuits and complete three circuits in total. ‘I’ve seen some great results from this but it’s not an easy option. You need to work at 90 per cent intensity,’ says Roberts.
