A 93-year-old British man is crediting weightlifting with improving his quality of life.

In an interview with the UK-based news outlet Luton Today, published on Aug. 14, John Jones raved about MolyFit. The functional therapy session led by sports therapist John Molyneux is designed to help people with Parkinson’s “live well” and get their confidence back.

Parkinson’s is a movement disorder that worsens over time, with symptoms including tremor, slowed movement, rigid muscles, poor posture and speech changes, according to the Mayo Clinic. The causes of the disease are unknown, but genes and environmental factors are believed to play a role.

Jones, 93, has been attending a joint Parkinson’s UK and MolyFit class weekly at the Bushmead Community Hub in Luton, England.

In a recent session, he completed a 40kg Olympic-style lift in seconds despite his Parkinson’s and arthritic knees.

“To be honest, in the beginning I wasn’t sure it was for me, but everyone’s enthusiasm was catching and John Molyneux’s coaching is gently persuasive,” Jones told Luton Today.

“And although I won’t be weightlifter of the year, my decrepit joints are responding, all be it slowly. But every little helps,” he said.

Molyneux added, “I knew they could all do it — the trick is getting them to believe that they could.”

He expanded on his thoughts in the caption of an Instagram post showing Jones lifting the weighted barbell.

“Today we deadlifted. I wanted to do a session to prove to the people in my group what they are capable of,” Molyneux wrote. “I wanted to show how when you believe in yourself, you can make great things happen.

“I started the session off by telling all the individuals in my Luton group that they would deadlift 40 kg,” he continued. “All of them did it. We have a mixed group ranging from a 93-year-old gentleman with an arthritic knee to a petite lady who weighs not much more than 40 kg herself…”

“Now, on a bad day when anyone in my group is feeling low, frustrated or needs a pick me up, all they need to do is look at their photo and remember who they are and what is achievable. #Parkinsons @parkinsonsuk,” Molyneux concluded.
