      How it works:

Your goals are my goals. When you come in we sit down and discuss what you want to achieve. With that information a program is designed for you and tailored for your specific needs. I will work with you and listen to you and guide you along as you get stronger and stronger as the weeks go by. Together with your feedback,  I will continue to tweak things and make gradual increases keeping your muscles guessing, mixing high reps and higher weights and mixing exercises continually. For your muscles to respond they must be pushed and kept guessing never becoming complacent.  In my gym you are not just a number here. Your progress means everything to me. I will listen to you and  work together with have my word.

​                      Overview:
I have 30 years in the fitness industry. 24 years training clients full time and 20 years
in the same location in beautiful Manhattan Beach. Park your car and walk 4 steps into the gym and you are working out instantly! Bonus cardio prior to your workout is just one of the perks at Body By Design. I am here to give you more....not less. If you like the idea of "cross-training" you will LOVE this! I 'invented' might as well call this 'criss cross training', because I don't always know, until I tell you, what is coming next. I encourage my clients to come in early for extra cardio. If you like a mixed up workout you will definitely like this. I promise to work with you, giving you your best workout within YOUR bodies limits. You definitely will know you were here the next day!
