A young boy and a baby kick on a bed and it is a sight to see. How adorable! These two have realized at a young age that exercise is extremely important and they have made it a part of their daily routine. From what we can see they take their workouts very serious, plus they have so much fun! These parents must be so proud! Another amazing thing is how perfectly they get along. Siblings usually have some disagreements when little, but these two have no problem with that. They are having so much fun together! It is true what they say - A sibling is a friend for life. And in this case, it is also a workout buddy for life! If they continue working out like this, they are on a good way to become serious athletes. It is important to start on time, and these two have definitely done that.
