“I met William after an Aqua Aerobics class at the Harlem Y. I noticed his Personal Trainer T-shirt and asked if he could help me strengthen my shoulders, which I had injured playing water polo. He signed me up right away, and I’ve been training with him ever since.

With William’s guidance, I’ve not only strengthened my shoulders but also my abs and back. My posture has improved tremendously, and at 60+, I didn’t think I could still lose so much weight and tone my body — but I did! I went from a size 14 to a size 8, and I feel stronger and more confident than ever.”

“I don’t give my endorsement to many people, but I want the world to know about William H. Felder III. William trained me for the 2006 Marathon, and with his help, I achieved my best time ever. He is extremely knowledgeable and has a unique ability to motivate you to go beyond what you believe is your potential. I highly recommend his personal training services to anyone who wants to get in shape and is willing to learn.”
