If muscles did not generate opposing forces, then the contraction and relaxation of muscles leading to movement will be limited.
Explanation:
Basically skeletal muscles work in pairs of agonist and antagonist muscles which work together but with opposing forces to contract and relax respectively. These opposing forces help to facilitate movement. Like in a bicep curl, the biceps work as agonist and triceps work as antagonist. The muscular strength is the force that acts against the opposing force of muscles. This strength is regardless of age, sex, weight or size of an individual.
