after like 2 years of only lifting weights i decided to do some HIIT today.I did it but at the end i chest hurted really bad from the inside, Is this normal? this happens because im not used to do any cardio?
no. that happens even if you used to do cardio.
>I did it but at the end i chest hurted really bad from the insidelolso normally your chest hurts from the 'outside'?
>so normally your chest hurts from the 'outside'?when you are sore. yes
this is a sign that it is working...just be sure not to do it everyday cuz its stresses your body too much.
