WEIGHT - HOW MUCH IS RIGHT
|Barbells||Involves dynamic balance; permits unconstrained movement and complex motions involving multiple muscle groups.||Often requires spotter; can limit range of motion; allows one side to carry the load for the other. Can present varying load over arc of exercise.|
|Dumbbells||All of barbell advantages, plus; allows extended range of motion; isolates each side; typically doesn't require spotter.||Places a lot of demand on the wrist (this may be seen as an advantage); usually decreases total amount lifted for a given exercise; can present a varying load.|
|Cables||Provides steady load regardless of direction of work; permits working with gravity - high pulleys; good muscle isolation; safe.||Sometimes difficult to maintain; motion is constrained to machine configuration, beneficial complex motions are not available.|
|Exercise Machines||Safe; easy to adjust load; isolates muscles; no spotter necessary||Motion is highly constrained; unnatural motions can result from improper setup; dynamic balance is not employed or reinforced.|
|Resistance Bands||Lightweight; portable; inexpensive; versatile.||Load varies with range of motion; not rugged.|
