I am assuming you all know how to warm up properly, so do a thorough warm up lasting around 5 – 10 mins. Then try this work out 5-7 days per week and you will see some fat Loss. Its intense for the time you are working but it is very short and so you should easily be able to fit it into your routine. It is based on the principles of a Japanese researcher called Tabata, although varies somewhat as you will not be able to put in max effort like he says, as you will be doing resistance exercises not sprinting.
Push ups – 20 seconds
rest 10 seconds
Body weight squats – 20 seconds
rest 10 seconds
repeat this sequence for 4 minutes flat out, only having those 10 second rest intervals. Then rest for 1 minute and use the same protocol but for the following exercises.
Lunges
Plank
This will be hard but remember its only 10 minutes of your life!
