That’s how I started exercising! I bought a smol dumbbell and did some light stuff with it, stopped for a while, picked it back up, and eventually, it turned into a habit. I’m by no means a strongman or a powerlifter, but I’m in decent shape, have a (very small) home gym, and started going to an actual gym with way more equipment this year (why did I waste time and money on a home gym?). It’s fun, keeps me busy, and is good for me. It’s also a great feeling when you see your lifts get heavier and heavier over time!
