I have a 16 month old (27 lb) toddler that wants to be a part of EVERYTHING I do! So.. While Holding her, I do squats! I do 2 sets of 10 to start off (you try it holding 27 lbs!).. And while counting out loud, I'm also teaching her NUMBERS! She loves it and thinks its a learning game and I get to burn away my thighs! Now that's multi-tasking!
