Does workout helps?

Hey fit freaks, I need some genuine advice and motivation.

I was quite fit and lean before, and even my face looked healthier. I used to get lots of compliments too. But in the last 1.5–2 years after college, my weight increased drastically. I’ve got stretch marks, face fat, hair fall, and honestly I feel like I look older than my age now.

I’m planning to seriously start working out and improve my lifestyle. Will it help me get back in shape and feel better again?

If anyone has gone through a similar phase and made a comeback, please share your experience or some insights. It would really help and motivate me positively.
