America's sweethearts of the 2012 Olympics--Gabby Douglas, McKayla Maroney, Aly Raisman, Kyla Ross, and Jordyn Wieber--made their unprecedented mark on the sport of gymnastics when they took the gold as a team in London almost four years ago.

Each of them endured their own unique journey leading up to and following the Games, all of which have been followed by the gymnastics community and beyond. Wieber is currently a team manager at UCLA, Maroney has moved on from her gymnastics career, and Ross just announced her retirement from elite and will joining the Bruins in the fall. Raisman and Douglas are the two remaining U.S. National Team members who are making a run for Rio.

Both Raisman and Douglas could be considered "old" in a sport that has been known to have its athletes peak at age 16. However, we've seen for several years now that this is only a predisposed idea.

At ages 21 and 20 respectively, Raisman and Douglas are two of the most promising Rio hopefuls, and they definitely haven't lost their mojo with age.

Check out these 'Transformation Tuesday' videos that prove it:

Will we see these two Fierce Five returners make a second Olympic team?
