A new study out of Norway suggests that you only need TWELVE MINUTES of exercise a week to stay healthy! (According to The Telegraph )
In the study, people who worked out as INTENSELY as possible for four minutes, three times per week, saw SIGNIFICANT improvements in their health!
Here is an extremely tough, but QUICK, 4-minute workout:
:60 - Pushups
:60 - Box Jumps
:60 - Shoulder Press (45lb or less)
:60 - Mountain Climbers
Do these with as little rest in-between as possible. You'll be VERY fatigued...although I admit that it's tough to hit the gym with this kind of intensity each time...but it's worth a try!
