Carmen's right - training Infernape in its defenses is absolutely pointless since you'll still get murdered all the same, especially since Infernape's two most commonly used physical attacks wound its defensive capabilities even more, with Flare Blitz delivering heavy recoil damage and Close Combat burning your defenses down to near-zero very quickly. Infernape should only ever be trained in Attack, Sp.Attack and Speed - training in any other area is a complete waste of EVs.
Also, the Clinic is for moveset and team-building advice only. It is NOT for advice about EV training or anything else that isn't movesets. This will be moved to the appropriate board.
