At first glance, the most obvious difference between bilateral and unilateral contracts is the number of people or parties promising an action. Bilateral contracts need at least two, while unilateral contracts only obligate action on one part. The other differences might be a bit more subtle.
Bilateral exercises work both sides of your body, as both limbs share the stress of the exercise. A barbell biceps curl is a bilateral exercise; a dumbbell biceps curl is a unilateral exercise. A bilateral exercise can be a multi-joint or single-joint movement. The barbell biceps curl previously mentioned is a single-joint bilateral exercise. The squat is a multi-joint bilateral exercise.
