I do legs once a week. Typically front or back squats, machine leg press (I do each leg separately), farmers walk w/barbell on shoulders, and machine calf raises. Next day & a half to two days, no soreness. Then, 3-4 days of severe quad, glute, and hamstring soreness. So bad I can barely sit down to take a dump, let alone get up afterwards. What, if anything, should I alter? More frequent leg days? Less reps? Less weight? Fewer exercises? Thanks for any advice.
