Well that's probably the most important thing. It won't hurt you and if you enjoy it there's no reason not to lift.
If you want to get faster on the bike though, I suggest you would have far more success following Hunter Allen's:
The Next Level. It's tougher than lifting 3 times a week but more productive.
