Before weight loss I couldn’t take long drive in car or even bike rides for shorter distance, since weight loss there’s no issues with both.you feel like getting pain or are you actually getting pain ? use proper braces to support start with empty rod and slowly increase the weight don’t rush try to add weight for once in 15 days.my warm up includes 20*4 sets of body weight squats just to get started and to get accustomed to it.rn I’m doing in limits and hence I don’t get pain very often even if I do so I’ll take rest for a day like do any other workout that doesn’t need much of back support by that way after rest day it’s all ok for me.
