Question:

I was told when I do my resistance training that I should do multi-joint exercises. What does this mean? Are there single joint movements? Iím a little confused; can you explain? (Lee, Bethpage)Answer

ANSWER:
Multi-joint exercises require the use of two or more joint motions in order to complete the exercise. Simply put, itís a compound movement. For example, a squat which involves: hip, knee and ankle uses more muscles. On the other hand, a single joint motion is an exercise that utilizes one individual joint motion to perform the exercise, in other words, isolation exercises. For example, a triceps press down isolates the triceps or a leg extension isolates the quadriceps.

Itís good to use both compound and isolated movements when you train. But if lack of time is a consideration, then opt for compound movements Ė more muscle bang for the buck. Also, compound movements prepare you for activities of daily living.

Compound movements: Bench press, rowing exercise, squat and military press.
Isolation movements: Biceps curls, triceps extensions, lateral raises and leg extensions.
