Quick cardio question

I know its supposed to be low intensity, 40-60 minutes. I am badly out of shape....so if I jog for about 2 and half minutes then walk a minute then do this over and over for the 40 minutes (my heart rate is always kept up and my chest hurts nicely...)does that sound alright, or should you NEVER need to walk and I should just jog a bit slower? Are you supposed to stay in your "target heart rate" thing during the full 40 minutes?



Oh yea....and does anyone know why my shoulder joints hurt like hell when im jogging? Im pretty sure im not bouncing my arms or anything weird like that.

only if your trying to maintain muscle.

Yeh stay in your target heart rate for burning fat so you can maintain muscle, muscle will help keep your metabolism up and aid in future fat burning.

Alright. What about that weird shoulder joint pain

I say stay in target heart range (for fat burning), if you don't like running but want to use a tread go at a slower pace but use the incline. I always wear a heart rate monitor when I do my cardio.

As far as your shoulder pain, could be the way you're moving your arms kinda hard to tell though.

Yeh you might wanna go see a doctor or something about the shoulder pain.
