The biggest benefit is the energy you have.
It also comes with an increased sense of well-being and self worth.
Ive been sleeping much better since Ive been getting fit.

Very nice side benefit.
2.Ive become much less clumsy.
Apparently using your body more makes your brain more aware of it.

Sex gets a lot easier.
Less like a chore and more like a fun exercise.
4.How much it takes to get me tired now.
I used to feel sluggish midway through work.
Now Im more energized.
5.Easily finding clothes that fit, and also actually feeling comfortable in your body.
And I mean physically comfortable, not just mentally.
Id shift positions and still feel the same.
6.The sex is so much better.
My dick seems bigger.
And I like feeling myself in the shower and stuff.
7.Honestly, the biggest advantage for me was how I can fit almost anywhere without touching anyone.
For an introvert, this is a godsend.
Eventually you start looking forward to it rather than dread it.
9.Food starts to taste better.
10.General mobility is so much better to climb ladders, bend over, wash your body in the shower.
11.Social life, dating, hunger, happiness, good skin, fuck everything gets better.
Machines are made for working.
If I havent been to the gym in a week everyone knows about it!
13.Shaving my legs is easier.
My belly doesnt get in the way and my legs have far less fat!
14.My posture is way better.
Used to have very weak back muscles, and standing with proper posture was exhausting so I didnt.
Now its the default.
Also, standing properly just by itself makes you look much trimmer, so thats a big plus.
15.Youre more motivated to do things that require energy.
At least, for me.
Things like walking the dog around the block suddenly became an opportunity to move rather than a chore.
16.My ass looks great.
17.Getting out of bed in the mornings feels so much easier.
18.Amazing how just about everything you do is easier.
And you didnt even know.
But now, the door opens easier.
Yeah, comes straight across and clicks in with zero effort.
Getting dressed in the morning and no sitting down to put the pants on.
The 20 min walk to the office when its 90 degrees out?
Not a single drop of sweat.
Its all just easier.
19.Being able to walk a lot more without my legs chafing.
20.People listen to you when you speak.
I didnt notice this while overweight but after losing the pounds it was obvious.
21.I can go longer without getting hungry.
22.Can fit between parked cars.
23.The biggest benefit is the energy you have.
It also comes with an increased sense of well-being and self worth.
24.Cuts on my body heal twice as fast when Im running 30-40 miles per week.
I can also remove the lid off of a jar of spaghetti sauce, no problem.
25.I stopped snoring/ having to use my CPAP.
Wonderful and totally unexpected.
26.Honestly just enjoying looking at yourself.
27.Spending significantly less time deciding on what to wear.
28.Most surprising thing was the space between the steering wheel and myself got a lot bigger.
Didnt think of that until I was driving to work today.
29.Insane horniness and rock hard erections.
Im still quite overweight but exercising every day turns me into a fuck machine.
30.Fewer to no back problems.
Im a 22 year old IT student so I mostly sit.
My back started hurting so much at the and of the day that I started to see a doctor.
Once I started working out, all the back pains disappeared immediately.
The second I notice my back hurting again I know Ive been slacking and go to the gym.
31.Severe anxiety = Gone.
May not be the case for everyone, but it has majorly helped me.
32.Your knees dont hurt when walking up stairs.
33.Not wheezing when you eat.
Or tie your shoes.
34.I have less (see: NO) acid reflux and fewer heart problems.
35.You get more enjoyment out of blowjobs when you might see your penis.
37.I poop so much less.
Less often, less volume.
Because I eat less.
Turns out when youre consuming 1600 instead of 3500 calories a day, you poop less.
I dont know why this surprised me, but it did.
38.I can see the dimples in my face again when I smile.
40.Blood pressure improved dramatically.
42.Putting on socks and shoes.
My gut doesnt get in the way anymore.
43.The air conditioning is brutal.
I always have to wear a jacket now.
Im scared of whats to come in the winter months.
45.I have so much more energy, I almost never feel lethargic.
I almost forgot I could dance because Ive been out of it so long.
48.The amount people seem to care about you grows immensely, which is pretty disappointing.
To paraphrase Henry Rollins, no one can lift that weight for you.
Whatever life throws at you, whatever happens, you and only you earned being in shape.
You cant buy it.
You cant get it given to you.
The only way to obtain it is through putting in the work.
That alone does wonders for your mental health.
