I follow a push/pull/legs routine and ever since adding higher rep trap bar work (6-15) legs days have been an issue. When weight starts to get heavy I get a slight stabbing pain in my lower back right at the waist (right side) I do not feel anything with lunges, BW squats or even lower weight on the bar. I do not know if it is a lower back problem or if it is just to fatigued from the t-bar rows and trap bar work. I train at home so the squat has to be used.
What would be the best solution? Do Legs, Push, Pull, Rest? Push, Pull, rest, legs? Maybe it is a back issue that needs to resolved?
