Why is cardio vascular excercise so hard for me?

Question

it seems lifting weights is easy for me,but running is hard...

Answer 1

circuit training allows for cardio while using resistance

and a fast paced walk will suffice in lieu of running

much easier on your joints

Answer 2

well your body has to get used to the running first. it is always going to be hard when you start. with more practice it will get better,trust me i know. but until then run in a pace you feel comfortable but not too comfortable. so be a little patient with it. good luck.

Answer 3

running isn't gonna be easy unless you run a lot.

Answer 4

maybe you should start easy and work your way up for more cardio time
