Step two is check out the mechanics. Just because you pay for lessons doesn't mean you are getting quality instruction. I have no clue who is giving the lessons but make sure they are reputable and know what they are doing. To be honest I don't see how he can really learn anything in a half hour session once a week. Is he doing drills, is he throwing and the guy critiques, is he breaking stuff down to understand...... Typically you get lessons for an hour and if the lesson starts at 6:00 they want you loose at that point. They don't want to spend part of the hour waiting on you to get loose unless it's early and they are teaching that aspect to you.
COACH2709 posted this in response to another thread about elbow pain. We have been fortunate in avoiding bad instructors due in part to avoiding lessons in general and some luck in selecting. What COACH says above seems obvious, but it got me thinking that lots of folks just starting out may have very little insight into what they should be looking for in an instructor and what cues to look for and which ones to run away from. The 30 minute lesson without any "homework" at the age of 12 would seem to be a less than ideal situation. Figured I would start a thread and let folks outline their thoughts on what is good and what is bad at a very basic level (i.e. local instruction).
