would doing 10 pull ups a day make any difference from an excersise perspective or am I just wasting my time?
Yes.
Eventually that 10 will become nothing, then you'll be doing 15, then 20, then 25, then 30.
Take it from someone who runs every single day. My jog used to be 5.5mph roughly an 11minute mile. But I was just jogging, not sprinting or even running hard.
My running, breathing heavy, puttin stress on was like 6.5mph a little over a 9 minute mile. Keep in mind I run 5 miles minimum so I'm conserving energy.
Now my casual jog is 7.5 mph which is just at 8 minutes.
