Dumbbell punches? Smart move. Punch up your health with a set or two. Just flex your arms and punch the air one arm at a time (don’t swing too hard though). At work, hold onto a stapler, tape dispenser or other object while you punch for an added workout. At home, if you don’t have dumbbells, just use cans or condiment bottles as weights!

Adults need 30 minutes of physical activity every day. Kids need 60.
