Join me in the “Sunday Birthday Challenge”! Do the following exercises listed every Sunday based on how old you are. (For example, if you are 45, do 45 of each.) They do not have to be done at once. You can split into two sets (ie 26 each) and do 45 crunches in between sets and at the end. Be sure to stretch first. Age is just a number! Have a great Sunday! PLEASE SHARE!
