I started the StrongLifts routine about a month ago, starting with 50% of my 5RM instead of the empty bar. Adding the 5lbs per workout has increased my squat 5x5 weight to a high enough level that I'm beginning to feel sore the following day and even during the next workout. I've always wanted to add sprinting, ideally on one of my two consecutive rest days (the weekend) but I'm afraid that this might interfere with the leg recovery.

Just wondered what other people have to say about this. I doubt it matters, but my last 5x5 for squats was Nov. 16 with a weight of 185lbs. Still not challenging yet, but its effects are showing through on rest days.
