Is this a good amount of exercise?
I'm an 18 year old girl and everyday I do:
100 push ups (not all in one go, I can only do about 40 in one go)
100 sit ups (in two groups of 50)
20 pull ups (in 2 groups of 10)
Lifting a 15lb weight above my head 100 times with each arm
I also go for a 5km run once a week
Is this a good amount of exercise or do I need to do more?
