20 minute chest & back workout with weights for those with cranky shoulders

All you need for this workout is a pair of dumbbells, but if you have several pairs of dumbbells, a Swiss ball, yoga blocks (if you are advanced at push-ups), grab those too. People who have never lifted, to bodybuilders, can do this workout, just choose weights that fit your current strength level, follow along, and listen to your body. Strength takes time, enjoy the journey.
