    I'm weighing getting a second physio/Swiss/balance ball. I am 6'1 and have a 65cm ball that I use for abs, pushups, ham curls and supine bridges. I find a 65cm ball makes pushups (hands on the ball) a bit too easy, whereas pushup are harder with hands on the 55cm ball in the gym. Ab exercises feel weird, however, on the 55cm ball.

    I'm curious if anybody uses different-sized physio/Swiss/balance balls depending on the exercise?

    For ham curls, I found smaller balls much more challenging. They are much harder to stabilize and force you to use your core more than a bigger ball. I think that'd be a good rule of thumb: if core stabilization is at the root of the exercise, smaller will be harder. Compare that to push ups (yes, there is a lot of core stab., but it's countered with scapular stability, etc...).

    For things like crunches on a swiss ball, I found smaller balls to be hard as well, but for different reasons. Depending on what (and if) you anchor your feet to, a smaller ball will let your legs provide less leverage to your core. Consider a large ball with anchored feet and no ball with anchored feet (straight leg) and that's where the difference in leverage come in.
