Saggy skin

[loopshot]

So I'm 42 year old and my body looks older. It's not to bad in clothes it's when I'm in bikinis.
My weight has been up and down over the years. From 9st up to 14st. Also 3 pregnancies.
Im currently 10st10 which im happy with, the problem is my skin looks quite saggy on the top of my legs (inner thighs), my arms, underneath and obviously my stomach from have 3 children, all c-sections.
Anyone know have any good exercises I can do to try and make these areas look a little better.
Must admit I've never really exercised in my life, can never find the time

I guess you also never find time to watch TV, or to be fair, post on MN ...

Tummy sag: I'm under impression only a tummy tuck can fix it.

Arms, legs : can be toned with exercise. Anything you can enjoy or at least not find annoying is suitable. Youtube would have body-area-specific videos. fwiw, I see very age 50+ people with sags in odd places. Don't expect miracles.

If it’s loose skin then it can’t be toned unfortunately.

I actually writer this thread whilst laid in bed. Looking after 2 toddlers and work full time no I don't find time to exercise or watch tv. Thanks

I lost a lot of weight and had saggy skin on my upper thighs, arms and tummy.

After 5 years of working out (running and weight lifting) I managed to improve the look of my arms a hell of a lot (built muscle, they look normal and toned now) and legs look better, am comfortable in shorts now (built muscle on quads) but absolutely nothing has helped the tummy sag, I'm actually booked for an abdominoplasty consultation next month.
