I always look to develop combination exercises that get you two or even three moves for the price of one.
This shoulder workout gives you six for one.
With this workout, you need to start with light weights — not only to make it through the number of repetitions but also to ensure that your technique remains good.
This is not for the faint of heart. You move from one exercise to the next in a smooth flow without rest: When you’ve done all six once, that’s one rep. Then, without rest, start over. The first time you try this, make your goal six reps, for one total set.
When you can do one set comfortably, take a one-minute rest and go for a second set. After two sets, experiment with heavier dumbbells and more reps — eight reps with heavier weights for strength or 12 to 15 reps with lighter weights for endurance.
