Ask the Personal Trainer Joni Hyde is a Certified Personal Trainer and owner of WorkoutsForWomen.com Q. You have talked about circuit training for women which I have started. My question is at what point do we increase our weights we are using and how do we know? I hope to hear from you. You give me motivation and have great topics. -- Cindy A. Since you're training for shape and not bulk, your strength training workouts should consist of a 15 - 20 repetition concept. If you can perform those 15 - 20 repetitions without feeling challenged, then you should increase your weight slightly. On the other hand, if you can't make it to 15 repetitions, then you need to drop your weight back a little. That 15- 20 range is perfect for ladies who want to create a leaner, shapelier and stronger body.
