My weight training now I'm on the bike a lot is just very basic maintainence strength work, typically once per week 2 to 3 x 5 deadlifts (which is possibly the hardest bit), something like 2x10 squats with dumbells, 2x10 lunges with dumbells , a bit of various bodyweight / core stuff, and done, all in half a hour tops and far away from failure.
If you're getting DOMS you're doing too much one way or another... and the day after I personally prefer to do an endurance zone ride / run rather than intervals.
