“I'm too big to start.”

There's no size you need to be before you're allowed to walk. Check your treadmill's weight rating and start slow. You already qualify.

There's no weight or size you need to reach before you're allowed to walk. Check the maximum user weight on your treadmill (it's usually on a label near the base or in the manual), start slow, use the rails if they help, and talk to your doctor if you have joint, heart or other health concerns. Larger bodies also burn more energy for the same walk, which is a real advantage.

Try this

Look up your treadmill's weight rating, then walk 5 minutes at a speed that feels easy.
