>>74130735i've been doing bicep curls with a bunch of milk jugs filled with water in a grocery bag.
i've only been doing it for a week or so but it's made a huge difference.
i went out and bought 50 lbs of sand so i could fill the jugs with sand instead of water. sand is about twice as heavy as water in the same volume.
now i want to work on my forearms too.
