That explains my muscle development after having kids. Basically just doing squats and lifts throughout the day. Lots of tag based cardio to round it out and those multiple peanut butter and jelly sandwiches every day probably helps as well.
But I am saying that I'd rather jump off a bridge than combine two of the most hated things in existence.
When I re-scanned myself after about 2 years off, I had gained quite a bit of fat and lost muscle in most places, but gained muscle in my arms/upper body. I felt notably stronger from carrying her (and her growing older sister) and that confirmed it.
