Flabby underarms in Seniors What kind of exercises can I do to decrease the flab under my arms or “wings”. Comments for Flabby underarms in Seniors Average Rating Jul 28, 2011 Work on those flabby arms. by: Douglas Schrift Yes, summertime means short sleeved shirts and exposed arms. Toning flabby arms can be done with exercises for the upper arm. My two favorite exercises for the upper body are the simple bicep curl and overhead lift. Bicep curl: Women can start by holding a 3 to 5 pound weight and men can start with a 5 to 8 pound weight with the right hand by your side. Slowly bend the elbow bring the weight to your shoulder. Perform 3 sets of 15 repetitions, 3 to 5 days per week. Overhead lift: Using the same or lighter weight, hold your hand at shoulder height and then lift overhead, extending the elbow. Perform 3 sets of 15 repetitions, 3 to 5 days per week. You will notice a significant increase in your strength and flexibility in 4 to six weeks. Good luck!
