Beginning – (my grandma) Holding two lightweight dumbbells or no weight, stand with your feet shoulder width. Bend at the waist with a flat back and your knees a little bent, reach as far as you can towards your toes so it stretches your legs, then stand.
Intermediate – (my mom in the middle) Holding two medium weights, stand with your feet shoulder-width apart. Bend at the waist and reach down towards your toes with a flat back and a slight bend in your knees so it stretches the back of your legs, then stand.
Advanced – (me) Holding heavy dumbbells, bend at the waist and reach all the way down to your toes with a flat back so it stretches the back of your legs. Keep your legs as straight as you can, then stand.
