And it's probably because of his lifestyle.
So instead of hitting the gym all the time, he just stays active.
Paul Walker's outdoor training regime
If your gym routine is starting to pale, head outside to add variety and excitement to your regime. Like Fast Five star Paul Walker, you'll burn more calories – and put an end to exercise ennui
The Hollywood star hasn't set foot in a gym for years, yet he retains his action hero physique
The obvious question: how can you look like Paul Walker? The face, unfortunately, we can't help you with. And as he doesn’t have a nutritionist or a personal trainer we can’t refer you to an eight-step workout. But he does have a program, a very effective and simple one: “My motto is, you have to do a sport every day,” he says. “Playing a little basketball, volleyball, going out surfing, skating, whatever it is. It’s the best way to live.”
Muscles worked shoulders, back, arms, lower back, abs
Benefit: “It looks as if the paddle stroke is all arms, but the power actually comes from your torso,” says kayaker Ben Selznick, star of the movie Nurpu: Extreme Kayaking. “As a resistance exercise, paddling works both sides of your body while strengthening your core, giving better posture and tighter abs.”
Muscles worked quads, hamstrings, calves, chest, abs
Benefit: “You won’t break a sweat diving, but you will burn calories; your upper body will get a workout hauling the gear out of the water, and your lower body will see heavy action finning against currents,” says Travis Gainsley a PADI master diving instructor at Pro Dive USA, Fort Lauderdale, the world’s top scuba training centre. Plus, scuba is a mind-body relaxation exercise. “Underwater, there are no phones and no emails. It has a Zen aspect.”
Muscles worked quads, calves, hamstrings, glutes, hip flexors
Benefit: “A major part of mountain biking’s appeal is that it’s a fitness sport, an exploring sport and a technical-skills sport, all in one,” says Mountain Bike Hall of Fame member John Stamstad. “Besides being a hell of a cardio workout, mountain biking improves your balance, coordination, and reaction time.”
Muscles worked arms, shoulders, back, abs, calves, quads
Benefit: “When you’re a beginner, surfing is a total cardio and upper-body workout, because you’re constantly paddling out through the waves,” says Scott Adams, a sports scientist specialising in strength training for surfing. “It’s a complete upper body aerobic workout that’ll make you incredibly fit. And once you’ve learnt to ride the waves back to shore, you’ll develop core and leg strength and balance, too.”
Muscles worked hamstrings, quads, calves, abs, ankles
Benefit: On the surface, boarding doesn’t seem much like a workout: ride a lift or cable car up the mountain, then slide back down. Not so says Adam Gendle, former professional snowboarder and director of snowboarding movies. “Putting in turns on the board works your legs and hips and you’ll use your abs to get back up after you wipe out.”
