Should be more than fine if you're training, depends how much protein you're getting from the rest of your diet but I really can't see 2 shakes being too many!

I already eat a pretty good diet, but I find with the ammount of exercise I end up doing from instructing classes (spin/Pump FX) etc on top of my own considerable ammount of training that I need to suppliment, else I'd get ill/injured/waste away.

I was never big into suppliments but my current work load leaves me little choice. On top of my usual food at the moment I'll end up having 2 shakes everyday and usually 2 protein flap jacks inbetween meals just to try and keep the protein and calories in.

Sometimes more if it's been a rough week and I'm feeling it (I eat more off how I feel/what I'm working on, I eat a base ammount and adjust with activity)

This is on top of 4 large meals. So yeah, I think you're good!
