I started doing deadlifts a few months ago. My back would round no matter what weight I did. I worked with it and 2 months in I can do ~155 without it rounding. That's pussy shit and I can definitely lift more, but I don't wanna fuck up my back. If I can't do anymore weight without it rounding, should I keep it light or move up anyways? Also, I've been following starting strength for the past 8 months or so (I didn't do deadlifts of power cleans for a while but finally worked them in more recently.) It's pretty legit and I'm definitely seeing results, but I want to start training more for the sports I do instead of gaining lots of muscle (doing both would be nice, but I know it's not gonna happen.) I'm about 20% bf right now, and I want to lean down and focus on getting in shape for mountain biking during the spring/summer and snowboarding/bootpacking which is pretty much highstepping uphill through snow for next winter. Should I change up the program and do less weight/more reps? Or just change my diet and consume less calories? Anything else I should do besides riding the stationary bike and using the stairmaster?
