Gym Reference

Okay here is where I stand at the gym. I am using this as a reference point for after the baby is born and I can get back at the gym. Right now I am running 3-4 miles at approx 5.8 mph or around 11 minute miles. I am doing 4 sets of 10 one legged raised box squats while holding a weighted bar over head. I can do 10 assisted pull ups with 25 lbs of help or 5 with 15. My goal has been and will continue to do an unassisted pull up or 10 one day. I am also doing 25 leg raise crunches with a ball between my legs in one set, then 15 and 10 for a total of 50. Weighted squats with 70 lbs on my shoulders. I weighed approx 110-113 lbs and was just under 19 % body fat. I'm scared about getting back into shape after the second baby is born. They say its harder the second time around.
