A training partner can be a great addition to your workouts, but there are some criteria that must be met before allowing that person to come on board.
1.) Similar Goals: If the person you are working out with does not have the same goals as you, the workouts are not going to be beneficial for both parties. For instance, if you are trying to add muscle and your partner it trying to drop fat, the workouts will not be congruent. It is your fitness goal that should influence the design of your workout.

"My initial thought about Keith was that he seemed very casual and not as frenetic as other professionals. I quickly learned that he was gauging my stamina, movements, and technique. He wasn't after a fast burnout, but he wanted to exhaust every muscle every time. He said we were working on a "mind to body connection." With this connection I'd be able to gauge whether a set was 15 reps or 20 reps regardless of the initial "goal of 15!" I believe much of my gains came from Keith always seeing my potential even when I couldn't." ~ Saul "Mr. Biceps"
