Democratizing Elite Training & Rehabilitation

The statistics paint a clear picture: tendinopathy is a widespread and debilitating condition, with 80% of us suffering a rupture by age 80. Driven by age and an active lifestyle, these injuries lead to reduced quality of life and increased risk of serious comorbidities. There is a significant gap in proactive strengthening and targeted rehabilitation to prevent and heal tendon injuries.

Over the last decade, we have been studying tendon and ligament adaptation to training. We have used these insights to guide top teams and athletes at the highest level across all major sports. Now, our goal is to create a device specifically designed to optimize tendon and ligament adaptation for everyone. Helping each of us train our tendons like an elite athlete.

We founded SinewUS to accomplish this goal.
