Down 50 lbs, do cardio and strength training at least 3-4 times a week but my inner arms and inner thighs are so flabby. Any ideas how to tighten them up a bit?

Water, Palmers Firming lotion, and hydration...and continued exercise. I know exactly what you mean...my arms are worse than my legs. Best of luck to you!

Oh believe me, after losing 137 lbs I have loose skin and its at its worst on my arms and thighs. I work out a lot and was lamenting the fact tonight that I finally have "guns" because my biceps are looking great but I can't show them off because of the underarm skin. Still, I'm going to give it a year before I investigate plastic surgery - from what I have researched it takes a good year before you know exactly how much your skin will shrink up.

With the bit I've lost I do have loose skin on the arms and thighs. But I just started with aqua fitness this week along doing cardio and the weight machines. More concern about my inner thighs too.

I don't know if it will help with the loose skin, but I've been practicing "horse stance", which is a tae kwon do move for several weeks now and I'm seeing improvement in the muscle tone on my inner thighs and glutes (butt muscles). I've also just started a 30 day squat challenge that was posted on FB. We'll see what the results are.
