What’s a girl to do on her down time in between performing? Play basketball, of course!. Britney Tweeted fans she wants to hang out on the court on Saturday.

Brit’s personal trainer, Tony Martinez, gave readers a few exercises he performs with Britney called the “Four B’s” – one of them includes B-ball.

– Basketball jump shot against the wall 20 times
– Backwards interval walking on a treadmill at 2.0mph for 1min then walk forward for a min.
– Balancing on 1 leg then with 1 arm doing medicene ball slams
– Bicycle and rotate on the floor mat for her abs 20 times.

Have fun, Brit!
