<human>: Here is a goal: How do I shovel snow and not hurt my back?

Which way makes more sense to accomplish this goal?

OPTIONS:
- Bend your knees and lift with your legs. As you lift the snow, keep the shovel blade close to you, to reduce back strain. Switch off between snow shoveling right-handed and left-handed, so that you're working different muscles.
- Bend your knees and lift with your legs. As you lift the snow, keep the shovel blade away from you, to reduce back strain. Switch off between snow shoveling right-handed and left-handed, so that you're working different muscles.
