Flabby upper arm pouch- help!

[Cornishbelle]

Starting to get the dreaded crepey upper arm saggy pouch just below arm pit to mid way down inner upper arm. I'm currently 3 to 4 stone overweight but am working on this and hoping it may help but then on the other hand could make things worse

I'm 43 - does anyone out there have any advice for specific arm exercises treatments etc that may help or have helped them overcome or improve this?

I'm in much the same situation and have just started to follow a 3 day programme on Strength & Muscle.com. Due to a shoulder issue plus tennis elbow, I'm using light weights; 1.5, 2.5 and 4.5 kg. I ache the next day but it feels good!

Tricep exercises with light ish weights will tone up that area
