If you’re too lazy to go to the gym but enjoy gym eye candy here is a very sad solution, the 20 second workout girls.
There are 4 to collect, each workout girls will work her little socks off for 20 seconds after a wind-up. If winding-up your girl sounds like too much hard work you might want to wait for Work Out Girl 2.0 with USB support (okay I made that bit up).
I do wonder who buys this crap stuff but if it’s you then they’re available from Gadget Shop for £3.95 (~$7.50) each.
