You squat, you press and you pull nearly every time you hit the gym. 
But when was the last time you took your weights for a walk? “Most guys never do,” says Dan John, a fitness coach in California, and the author of Intervention. If you’re one of those men, you’re neglecting a key part of building functional, real-world strength: increasing your carrying capacity. Put yours to the test with these farmer’s walk variations. “They’ll tax your core,” says John. “But done regularly, they’ll also strengthen it – which will make you stronger in everything you do.”

HOW TO DO IT
Start with the farmer’s walk, using two dumbbells that each weigh half your body weight. Walk 20m with perfect form. For an even greater challenge, try one of the other two tougher variations.
