What results am I expecting

>be me
>have extremely high metabolism (can eat anything for days and literally still stay unhealthily thin)
>my current routine:
1. 10 mins treadmill, settings: gradient 2, 9km/hr
2. 10 mins treadmill, settings: gradient 15, 6km/hr
3. 10-20 reps on chest workout (20kg lol)
4. 40 reps on the thigh workout (25kg)
5. 5 reps on the shoulder workout (15kg)
6. 10 mins on the rowing machine (max settings)
>currently been going to the gym for the past 5 days
>have super cold showers after each workout (if that helps)

What results should I be expecting and when should I be? How should I change this routine? I can go to the gym 2 hours a day, how should I exercise in regards to my body?

Thanks.

Even with those small workouts, btw, my arms and chest hurt like hell.

Why so much cardio? I think you want to get bigger, don't you?
Do brosplits, 5-10 reps to failure on every set.

Eat as much as you facking can, and cut out the treadmill if you want to get bigger
Also do weigts that you can't do over 5 reps of

Also maybe buy an quality mass gainer (one that isn't all sugar). I have a similar metabolism and since I don't have enough money to eat as much as I should nor do I have such a big appetite the mass gainer really helped me.

just to confirm, reps are the amount of times you do it

i don't know, i really want a strong heart, its a really big anxiety for me to have shit circulation, does cardio have any opposing effects to other exercises?

What are the the benefits of taking a cold shower after a routine?

no idea, read it on google somewhere, apparently it "helps the muscles"

It's a meme. Literally no benefits except a placebo effect. Try a ice bath though, that has legitimate science behind it for muscle recovery

do cardio when you've gained enough muscle mass.
cardio burns a fuckton of calories.
you need calories to gain mass.
