I'm in the same situation as you! It's because I'm too thin, and sometimes I get dizzy when I stand up after squatting for a long time. Now my skin is still loose, but I massage my legs and arms with Nivea's firming gel every day, and the fat on my stomach is ok, mainly in my limbs. I heard from friends that L 'Oré al's is also good, but I saw that the firming gel with the highest evaluation in books and online is the kind with delicate rhyme and is ready to run out. I have been massaging myself every day since last year, and then I go to the gym. My thighs and arms have tightened a lot, but you can't expect exercise to achieve a very fast tightening effect. I haven't changed much in the first half of the year, and the effect is obvious after half a year! We must persist! And you can't drink water after 8 o'clock every night, and you can't eat salty things at ordinary times!

Anyway, if you have nothing to do, just pinch your fat. If you want to tighten your skin, just exercise more. Come on!
