Try this:
have your partner hold the mitts with the palm side to his chest. Have him randomly feed you whatever he wants you to throw, then put the pads back against his chest.
for example, I hold the pads against my chest, then show one, for a jab. you jab, I bring the mitt back to my chest. I flash jab/cross/hook, you throw it, then I bring the pads back. If I leave the mitts out, you keep swingin until I hide them.
This way, you get to work your singles, your bread and butter, and throwing combos fluidly, as you won't know what your feeder is going to throw.
After you get used to this, have him add sound effects. For example, I feed you for a one/two and say "bop, bang". bop signifies a light hit, and bang a hard. So, in this example, light jab, hard cross.
