You know him as the thrill-seeking bad boy in HBO's True Blood, but before Hollywood, Ryan Kwanten had a stint as a professional triathlete. His pro-racing days have been over for a while now, but he trains like hes still competing. Kwanten prefers being outside and running on the trails instead of paved roads. Its less boring, and the rough and uneven terrain means no two steps are ever same, so it challenges more of the tiny muscles in your legs and feet. Kwanten has also been known to go swimming, bungee jumping, biking, and hes even in a bowling league. Hes got the variety aspect of his workout down. Which is important, because if your muscles get used the same workout every day, youll stop seeing results. Kwanten also knows that if you really want to build your best body, you have to fit in a few strength-training sessions each week. The good news is you dont even need a gym membership. Kwanten has said that he trains at home with classic body-weight exercises like pushups, situps, pull ups and jumping rope. He uses a thick rubber jump rope and does varied intervals - he may do one minute of double bounces and then two minutes of singles. In you dont have the skills for double-dutch just yet, Matt, one of my trainers here at Peak Performance, is going to help me give you a few pointers.First, your weight should be on the balls of your feet and your knees slightly bent. Keep your body upright, eyes front, and elbows close to your body. The movement of the rope comes from making small circles with your wrists. Dont jump more than an inch off of the ground and remember that your feet should only make contact with the ground as briefly as possible. Start with 10 sets of 10 jumps and gradually work your way up to 100 jumps nonstop. Eventually, you'll do up to 5 to 10 minutes of continuous jumping. You can burn the same amount of calories in 10 minutes of jumping rope as you can in 30 minutes of jogging. So not only does Kwantens workout build the lean, strong look that Hollywood loves, but he does it in less time than most other plans.
