Research question: Does bringing arms down in a bicep curl to 30 degrees, sixty degrees, or 90 degrees put the most pressure (force) on the bicep muscle as measured using a 5 kg weight, an 8 kg weight, and a 10 kg weight?

Design 1. Gather 10, 16 year old males 2. Have each male do 5 bicep curls at 30 degrees with the 5 kg weight, 5 curls at 60 degrees with the 5 kg weight, 5 curls at 90 degrees with the 5 kg weight, etc. Record all data. 3. Find the x and y force components of the bicep curl and average.
