We’ve been told our whole lives that the only way to gain muscle is by working out.

But now, new research from Harvard Medical School has sent the fitness industry scrambling:

If you’re a man over 40, working out might be a total waste of time. And shockingly, could even “speed up” age-related muscle loss.

We spoke to world famous men’s health expert and TEDx speaker, Dr. Tracy Gapin, about this astonishing discovery

“Sadly it’s 100% true”, says Dr. Gapin. “Past 40, exercise can actually cause your muscle fibres to break down. Leading to weak, small muscles and unwanted weight gain”.

Fortunately, Dr. Gapin – who has made headlines in Fox News and Entrepreneur Magazine – says there is one far easier way to reverse age-related muscle loss.

After over a decade of research, Dr. Gapin has released a video sharing a surprising “muscle-building shortcut”. Which men over 40 can use to transform stubborn belly fat into lean muscle.

This “shortcut” works by helping your body use the energy stored in fat to build muscle. And has already been life changing for over 3700 American men – including Dr. Gapin himself:

“I used to think the key to gaining muscle was lifting weights and chugging protein shakes”, he says. “But it was this simple shortcut which helped me shed over 40 pounds, and get in the best shape of my life.”

Dr. Gapin’s video has since gone viral, first being shared by users on Facebook, then on news sites like Fox News and CBS.

So far the feedback has been astonishing, with thousands of American men now feeling stronger and more confident than they have in years.
