When you’re slogging away at improving your fitness you want to be sure all that effort isn’t wasted.

It seems there’s a new way to get fit every day. Aerial suspension ran hot for a while, with people trying yoga or strength classes while suspended in reams of silks.

There are shake weights, rolling weights, or weights you can strap onto different parts of your body.
