It all depends. Try not to think of compacts and triples as training devices, but rather tools for different purposes. I still ride a compact because I climb some long and steep climbs.

If you're not using your easiest gear combination very often, you can find harder climbs to challenge yourself, or up your gears. For the latter, you have options:
- Change your front chainrings for a 52 and a 36 or 38
- Get a new standard crank with 53/39
- Change the rear cassette to a 12-23 for closer gear choices or 11-25/11-23 for faster descents
