My oldest child weighs about 40lbs and my younger about 30lbs. I’m working on finding some cheap weights to use but in the meantime a good way to play with the kids to wear them out before bed is to use them for bench presses.
We just did about sixty presses alternating between the two kids.
I’m no buff guy but I’d certainly like to gain some muscle over the next year.
If anything the kids got to have fun and I got a wonky workout.
