I do a 3-day split, and work out 3-4 times per week, meaning if I work out 4 days one week, I will have repeated the workout I started with. That is, no auxiliary routine for extra days, just back on the rotation.
My leg days have usually consisted of squats, then deadlift, then some auxiliary exercises. I then decided to alternate which exercise I stared with. Meaning, on the first leg day, I'd do squats then deadlift, and on the next leg day, I'd do deadlift then squats.
Recently, I've noticed that whatever I do second is going to be remarkably diminished, because my nervous system is already fried from the previous exercise, and I'll outright fail on reps at 70-80% of my max.
My new idea, which I need input on is maybe I should just do one of them, each leg day. Meaning if I do squats the first leg day, then I'll do deadlift on the next one.
My reasoning is that the two exercises both engage the lower back and legs, so it's not as if these two muscle groups are going to be resting for 2 weeks in any case.
I've considered maybe just separating squats and deadlifts into separate days in the split all together, but I've found that working these areas twice a week is too much, when I'm lifting weights this close to my max.
Any feedback or other ideas?
Thanks in advance!
