It takes strength from the deltoid and other muscles for a good port de bras. This is a simple, easy to do anywhere exercise to check the endurance of the deltoid muscle.
Make sure your shoulder is in neutral to begin and work your way up to 2 sets of 40 repetitions forward and 40 repetitions backwards before moving to other shoulder exercises. I was surprised when I felt fatigue with my initial 2 sets of 20 reps! Obviously haven’t been using my arms in the same way that I used to:)
Note when fatigue sets in. It won’t take long to get to 2 sets of 40 circles forward and backwards!
To your success,
