 * Question:** Which muscles are stronger, flexor or extensor muscles?

 * 1) Get into groups
 * 2) Have one person stand up straight with his / her back against a wall.
 * 3) Have that person hold the weights in his / her dominant hand
 * 4) In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
 * 5) Repeat steps 2-4 for each member of the group.
 * 6) Record the data for each member of the group.
 * 7) Have the first person stand as straight as possible near a wall.
 * 8) Have the student hold the weights with his / her dominant arm bent near the ear.
 * 9) In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.

 * Conclusion: I was wrong, the Extensor muscle is weaker then the Flexor muscle, because i did 54 curls with my flexor muscle and 32 exstebders with my extensor muscle.**
