This past Fall I was in full swing. CSSing every day, using those back muscles to swing the maul and chop the wood. I went through about 6 or 7 cords by hand. I have my three year supply. Now I can sit back and let the oak sizzle in the sunlight. But I’m resting. I don’t have to chop. I’m getting weak compared to last Fall. I’ll have to do some other exercises
