Off Their Rockers

Stand on a comfortable surface, where you’ve got some room to maneuver.

With a five-pound potato bag in each hand, extend your arms straight out from your sides and keep them up there as long as you can. Try to reach a full minute, then relax.

Each day you’ll find that you can hold the pose for just a bit longer. When it starts to feel easy, switch to ten-pound potato bags.

A week or two later, try thirty-pound bags, then fifty. Eventually, you can lift 100-pound bags in each hand, with your arms outstretched, for more than a minute!

(I’m at this level.)

As soon as you can handle this without straining, put a potato in each bag.
