Andy, While nothing can substitute for the hands-on experience of training a lot of clients, I might have something that will help with the confidence. Check our our application Elevation Fitness LLC I have loaded over 700 exercises here with full form cues as well as pictures. You can build workouts for your clients and brush up on the form for each exercise before you start the training. At the level you are at right now, you should qualify for our free account as well. Please let me know if you have any questions. David Schwendiman Elevation Fitness LLC (541) 908-1676 david@elevationfit.com Elevation Fitness LLC
