Hello guys first of all English isn't my first language so sorry for mistakes.
So my problem is I'm sitting in my ass for 3 years. I didn't go outside at all(except necessary things like buy bread or visit your friends, family etc.). And now I get tired so quickly for example today I go outside for buy a bread and then I got tired my feets hurts and I sweat so quickly(between market and my house is like 5-10 minutes). My height is 1.95 and my weight is 114. So my question is where can I start first? I tried some cardio things and I got tired quickly again and I couldnt do it anymore and I just scared for hurt my leg or something. I'm really open any suggestions guys. Thanks
