Not sure why you ask this from your profile info. Here's a genuine answer, not meant in any ways patronising or sarcastic...
Go walking, do ridges. Don't get a heavy pack on purpose: on the contrary get into good habits and start making it as light as is safe.
Re strength: go climb winter stuff lots. If that's not available (time, money...) do some dry tooling. At the very worse (which is already a lot) climbing will always be beneficial. If none of the above is available, keep generally fit, and have stamina.
Anyway, winter climbing makes you (for most people anyways) good at winter climbing.
