Strained lower back deadlifting few days ago. Ok today, did chest/delts/abs.
I recommend hitting some hypers with no weight just 14 15 reps to get some blood in the area and then prayer strectches. Hold the stretch for at least 45 seconds repeat until your lower back/hips feel good. Otherwise you will be in constant pain grabbing dumbells, reaching down to grab your water etc like I was.
