I'm a new father (7 months in), and sometimes struggling to pick up and carry my child (previously trained mostly for marathons, so I'm not blessed with copious upper body strength). As of now, the child weighs 16 pounds.
Since I don't have a gym membership or any free weights lying around, but I do have a convenient 16 pound weight in the form of my child (with the bonus that as she gets heavier, my workout weights will naturally adjust to demand higher load, rather than having to buy heavier dumbbells), will lifting her provide a good, baby-wrangling-specific workout?
How many reps and sets would be recommended? What exercises in particular are suited to lifting a (generally) cooperative baby? I'm not trying to bulk up, just have sufficient strength to be able to deal with the child on a day-to-day basis.
