As students at the University of Colorado preparing for finals -- beginning Saturday -- some already are less stressed, thanks to projects that replace the dreaded final exam.

Students in professor Rodger Kram's biomechanics class are done for the semester after presenting their final projects this week. Their knowledge has been put to the test, but they'll get to avoid a finals week exam thanks to their team projects.

For three of Kram's female students, their final grade will bank on a unique pair of high heels.

CU senior Alyse Kehler and her two teammates created a pair of high heels with removable heels, a creation the girls admitted they were fighting over as their class ended on Wednesday.

A pair of flats with a clip glued to the heel and stiletto-high bars that snap on and off for comfort are not only stylish, but comfortable for a girl on the go.

"We're really happy with it," Kehler said. "I wish I had a pair of them."

With a common goal of improving or reducing stress on muscle movement, other projects focused on subjects with a handicap to get the grade.

One team made an apparatus that straps to the shoulders of people without limbs, allowing them to attach golf clubs and get ideal aim by simply twisting their torsos. Another group created a faux pair of arms that can be worn to improve balance and consistency when walking and running.

The "Handy Standy" was created by a group that was trying to help a yoga instructor with a crippled hand improve

balance and stamina. And the "Ham Roller" massages someone's hamstrings during a long car ride, maintaining flexibility and comfort of the muscles.

One group even decided to take on one of America's biggest health problems: obesity.

CU senior Kyle Puntis and his teammates built a resistance suit, an orange jumpsuit with Pilates bands attached around the arms and legs.

"It makes everything more difficult," Puntis said. "This way they don't have to work out to work out."

The suit may not be as fashionable as the high heels, but Puntis said the functionality was there, and hopefully that will get them the "A" they're hoping for.
