Lennard Zinn Recommends Getting Your Human Frame Aligned by Correcting Your Leg Length Inequality

“I knew a lot about the negative effects leg-length differences have on cycling performance before I had my unequal leg-lengths corrected by Dr. Groover. Leg-length differences are a big bike-fitting challenge I’ve dealt with in my bike framebuilding company since the early 1980’s. Naturally, a way to correct these length differences on a long-term basis appeals to me.

For me, working with Dr. Groover is fascinating, informative, and generally very useful. I have been to Dr. Groover after many injuries about which I’ve seen many health practitioners. In almost every case, the unique way Dr. Groover explained the problem, treated it, and the rehab exercises he gave me made more difference to my healing than anything else I had tried.

From having my leg lengths even, my back pain is reduced and my pedaling is smoother and more comfortable. Dr. Groover’s adjustments hold for a long time — until my next bike or ski crash. I did not previously know how correctable most leg-length differences are (for the long term). I recommend Groover Clinic because Dr. Groover’s treatments are effective, and the beneficial effects are lasting. The benefits riders will appreciate the most are more comfort, especially on long rides – low back, shoulders, and neck, as well as a smoother and more powerful pedal stroke.

The quality of care at Groover Clinic is high. Its Physiological Short Leg Correction program gets your human frame aligned. The Groover's offer high quality advanced treatment programs for taking care of you completely.

To take care of your injuries, I recommend Groover Clinic’s advanced Holistic Injury Prevention and Treatment Program. Also take advantage of Groover’s Holistic Neuro-Muscular-Skeletal Performance and Wellness Program as a way to fine tune the way your body functions. And for optimizing energy production, power and endurance, try the Metabolic Performance and Wellness Program.

I recommend Groover Clinic to any cyclist experiencing back, neck, shoulder, or joint pain. But really, in my experience, almost anybody from their teen years on could benefit from it. That’s because due to injury, or to carrying a backpack or purse for years over one shoulder, or to other posture habits, almost everyone has their head carriage off and stands with more weight on one foot than the other. And, while I’ve been to many practitioners who would improve that temporarily, only Dr. Groover’s methods have ever made a lasting difference. My first correction from him held for two years!”

Dr. Groover Describes What’s It Like Working With Lennard Zinn?

Lennard Zinn readers and friends respect Lennard for his superb intellect, championship athletic ability, and generous, warm personality. I have been privileged to know this extraordinary man and to help him achieve his cycling and sports goals. Lennard and I work together to keep his leg lengths even, his spine and extremity joints and muscles healthy, to prevent him from experiencing sports injuries, and when they occur, to heal these injuries quickly and thoroughly.

Lennard was my first patient at Groover Clinic. He had already published a well-researched article in Velonews about one of my leg length corrective procedures, and was eager to have his uneven leg lengths corrected.

Come to Boulder, and get fitted for a Zinn Cycles custom bike (zinncycles.com) and visit Groover Clinic and I’ll balance your leg lengths. You will love the benefits you experience from your new, more symmetrical, more efficient bike/rider relationship, including smoother pedaling, and more powerful and comfortable riding.

Shortly after the rider's pain was eliminated, he felt and performed as well or better than he had since his 20s. Four weeks after beginning treatment, he recorded a new personal best, over 4% better performance during an 80 mile ride. The following day he rode 60 miles, 4,000 feet elevation, with much greater upstroke power, and no pain throughout the weekend.

54 Year Old Cyclist With Back, Hip, and Leg Pain

A 57 year old rider was particularly concerned about his moderate low back pain and numbness, radiating down the back of his hip and leg to his knee, and occurring 60% of the time. The man had been hit by cars twice while riding his bicycle and had injured his low back in a skiing accident. His distance riding somewhat relieved his symptoms, but he was still stiff and uncomfortable. He was concerned about future surgeries, worried about the impact this problem was having on his present life, and was unhappy about the effect his injuries were having upon the quality of his present life and the prospects for the quality of his life in the future.

After the rider received my first treatment, he said he felt only mild pain and numbness upon rising, and he had mild pain while bending sideways. He reported his climbing was more powerful, he had more symmetry in his cycling form, and he experienced considerably more powerful pedaling upstroke.

After the patient’s fourth treatment, he left my office pain and numbness free. He said he was riding as well or better than before his car and skiing accidents. He reported feeling as good or better than he had felt since his 20’s.

The rider had ridden 146 miles the previous weekend. During the first 80 miles of Saturday’s 86 mile ride, he clocked a new personal best, 18.8 miles per hour. His previous best was 18 miles per hour during the first 60 miles of the same course. He was riding 4% faster and covering 25% greater distance. On that Sunday, the rider pedaled 60 miles, 4,000 feet elevation. He reported he was pain free both while riding his bike and while resting during his entire weekend workout.
