Bruising easily / a lot?

It's never a surprise for me to get bruises. I'm very active in climbing and sports so if one pops up every now and then it's no big deal. But lately I've noticed that I've been getting numerous bruises all over my legs and now my arms. At first I thought it was just because my siblings and I have started learning parkour...but I'm a big girl - I've got some meat on my bones - and I have a grand total of 29 purple bruises on my arms and legs and each of them are painful. Should I be concerned about this? Is it something worth seeing the doctor for?
