defining muscles.

Don't go for Machines all the time though.

It's about what's safe for people to do, or okay to use. A Cable Row Machine is fine, but using machines that work Bi's and Tri's are crap.

A Pec Deck can be useful for Chest or Back, but Adductor Machines aren't worthwhile, so if you're training alone, maybe use 2-3 Machines, and add the rest of your workout in with Bars and Dumbbells.

ehhh, i'd say stay off machines, lift faster than 4 second reps, higher weight / lower reps than 8-10, and don't do negatives

Some people, like myself, don't have a workout buddy. Machines make it possible for me to even work out by myself.

then i'd suggest using lighter weights or different lifts. when i say avoid machines i primarily mean ones that are bad for your joints (e.g. smith machine) or ones that are basically useless because they only target one or a few muscles. free weights and barbells will help establish core muscles which so many people complain about and are more beneficial in opinion.

high reps between 12-15 reps.. of a lower weight
