@nedlm10 Magnesium as well. Great answers.
Keep us posted. I do need to add 2nd year of weights is easier for soreness. Try something gentler on in between days: rowing or walking.
@nedlm10 I dropped to 2 long sessions a week, gave up on the every 2nd day thing. Try maintenance for a bit, not thrashing yourself. Doms lessened considerably with more rest and electrolytes.
