When you’re working with a personal trainer, take an active role in your weight-training sessions, aligning your behaviors with a willing participant that trainers can easily work with. Keep these things in mind to ensure you have the best trainer-client relationship possible:
Show up on time. Trainers are professional people with busy schedules and bills to pay, so show them some courtesy.
Have a good attitude. Your trainer doesn’t want to hear you whine about your boss or your latest speeding ticket.
Listen to your trainer. When your trainer advises you to perform 12 repetitions per set, don’t say, “My stockbroker said I should do 40.”
Speak up. Don’t be afraid to ask why you pull a bar down to your chest instead of to your belly button.
