Aly Orady, Founder & CTO

Aly Orady is the founder and Chief Technology Officer of Tonal. In 2013, he developed the pioneering digital resistance mechanisms and initial algorithms that power the product today—setting the foundation for a new era of strength training.

Orady, a supercomputer engineer who struggled with his weight since childhood, managed to carve 70 pounds off his frame at commercial gyms. But when prolonged progress eluded him, he sought a paradigm shift that could help anyone create sustainable change in their bodies and minds. In the process, he revolutionized the realm of human improvement by inventing Tonal.

After exiting two prior startups, Orady led Tonal as Chief Executive Officer from 2015 to 2023, securing dozens of patents, fundraising, and overseeing the company’s senior leadership team, structure, and operations. Now in his role as CTO, Orady oversees Tonal’s technology portfolio as he carries on his mission to make strength training accessible to all.

Orady holds an M.S. in electrical engineering from Stanford University and received his undergraduate degree in computer engineering from McMaster University in Ontario. He is married with two children and is glad he can get the world’s best workout in the comfort of his home.
