Maybe we’re so soft around the middle because we have it so easy.
It’s been a long time since anyone in our tribe has had to fend off a saber-tooth tiger or wooly mastodon.
But maybe a little caveman-like behavior can tighten us up a bit.
A few fitness gurus have created regimens to replicate the tree climbing, rock jumping and barefoot running of our ancestors (in Vibram FiveFingers, no doubt).
You can pay for their camps or you can just take some time every once in a while and go Paleolithic:
Eat the way we did in the cave: Consume mostly meat, fish, fruits, veggies, and nuts. Avoid the easy stuff of that’s come with civilization, like dairy, grains and junk food.
Exercise like early man: Do whole-body exercises outdoors a few times a week: sprint, climb, swim, lift heavy things, jump and tumble in short spurts. Throw at a target. Wrestle and play with your dog.
Prove yourself worthy: Compete against yourself or a friend; find out who should lead the tribe. Stay involved in races and games. Workout before breakfast and work. Act like the animal you are.
