At first I feel my bicep and start touching. You can really see my muscle fibers pulling my finger out. I really push my finger inside my muscle which was kind of painful. Then I start flexing and deforming my bicep with my hands. At the end I make a long bicep contraction trying to maintain full power throughout. You can see my bicep fully contracted at the beggining and slowly failing to contract even though I am actually using all my power to. You can see me shaking and hear me struggling. At the end I wasn't really able to feel anything on my arm due to exhaustion.
