I've been getting a lot of referral business lately for personal training and I've been considering the things that make pt effective. Keep in mind some of these are not necessary for an effective exercise program.
So aside from tailoring a specific plan to your client's goals/strenghts/weaknesses:
Vary the exercises
Reinforce flawless biomechanics
Train close to failure or use high-intensity techniques
Use unconventional exercises
Spot every rep and apply touch training when applicable
Provide verbal coaching
Move quickly from one exercise to the next (superset)
Focus on compound movements
Don't count reps; instead, focus on technique and rep speed
