Lying down? In bed, on the couch or even at the beach, here’s how to take advantage of your horizontal time to work your core.

1. Start on your back, legs straight and arms above your head. Lift your head.

2. Then, slowly peel yourself off the ground. Move with control, aiming to rise up one vertebrae at a time.

3. Don’t yank yourself up with your arms; use your abs. Repeat two or three times.Carrie Cockburn/The Globe and Mail
