Want a killer workout?

Take your 3 boys (ages 15,12 &8) on a bike ride! I thought, "what a great family fun day with my guys"...omg they all try to out do each other which forced me to keep up with them-no way am I going to not take the trails and jumps they did-I'd be a wuss!! They are all very strong & healthy (and young!!!) I intended on being out for about an hour-turned into 3 and about 13 miles of some tricky terrain with one stop for about half an hour at Jamba Juice.....what a work out!! I really thought I was going to have to stick back with the youngest while the older 2 took the more advanced trails-but to my surprise the little guy kicked butt!! We all blazed the trails and nobody fell into the creek!!!
