OK, so ATP releases energy. At what point are things moving? How does this "energy" lead to a muscle fiber contracting?
How does the energy from ATP get to converted to mechanical energy?

SUMMARY
ATP hydrolysis is the primary mechanism through which energy is converted to mechanical energy in muscle contraction. The process involves crossbridge cycling, where ATP binding and hydrolysis lead to conformational changes in myosin motor proteins, facilitating muscle fiber contraction. Key insights can be found in the linked Wikipedia article on crossbridge cycling and a related discussion on molecular motor proteins.
PREREQUISITES- Understanding of ATP hydrolysis and its role in energy transfer
