Happy Hamstrings
Build mobile, stable, injury-resistant hamstrings — in just 12 weeks.
$49.95 / year
Happy Hamstrings is a 12-week guided video program designed to help reduce hamstring tightness, prevent pulls and strains, and build injury resistance throughout your posterior chain. Led by running biomechanics specialists Dr. Daniel Strauss and Austin, you’ll systematically address mobility, stability, and strength deficits that contribute to chronic hamstring issues.
This isn’t generic stretching—it’s runner-specific training that prepares your hamstrings to handle the repetitive loading demands of running.
- 12 weeks of video routines
- 3 sessions per week
- Mobility, stability & strength work
- Led by Dr. Daniel Strauss & Austin
Why Happy Hamstrings Works
Tight hamstrings aren’t just inflexible—they’re weak, unstable, or both. Generic stretching won’t address the root problem. Happy Hamstrings progresses through three phases: fundamental work that establishes baseline function, intermediate training that builds capacity, and advanced exercises that bulletproof your hamstrings against the demands of serious mileage. The result is hamstrings that stay loose, strong, and injury-resistant.

Frequently Asked Questions
This program is for runners who want to help build injury-resistant hamstrings, prevent past hamstring pulls or strains from recurring, or address restricted stride. It’s also perfect for runners who want to prevent these problems as mileage increases. Whether you’re managing chronic tightness or building injury resistance, Happy Hamstrings provides the systematic progression you need.
The program is designed for 3 sessions per week over 12 weeks, progressing through fundamental, intermediate, and advanced phases. Each session includes mobility, stability, and strength work specifically designed for runners. You can do sessions on the same days as your runs or on separate days.
Minimal equipment is required: resistance bands (CLX bands from Theraband or similar), a physio ball (highly recommended for later phases), and common household items like a step, couch or chair, and elevated surface. You can enhance exercises with optional gym equipment like weights, medicine balls, or balance pads, but they’re not necessary.
If you’re dealing with acute hamstring pain or a recent injury, consult your doctor or physical therapist before starting. This program is designed to address chronic tightness and build long-term resilience. Once cleared by your healthcare provider, Happy Hamstrings can help you address contributing factors and prevent future problems.
Chronic hamstring tightness is rarely just a flexibility problem—it’s usually a combination of mobility restrictions, stability deficits, and strength imbalances. Happy Hamstrings addresses all three systematically. Simple stretching only addresses one piece of the puzzle, which is why it often doesn’t work long-term.
Dr. Daniel Strauss and Austin are running biomechanics specialists and co-founders of Athletic Kinetics. They understand the specific demands running places on hamstrings and have designed this program with runner-specific exercises you won’t find in generic programs. Dr. Strauss is also a VDOT certified running coach.
Unlike generic hamstring programs, these exercises are designed specifically for the movement patterns, loading demands, and injury risks runners face. The progression prepares your hamstrings for the repetitive eccentric loading of running, builds stability through running-specific ranges of motion, and includes plyometric work that mimics the demands of actual running.
Absolutely! Many runners cycle through Happy Hamstrings multiple times throughout the year. Each time through, you’ll build more capacity and resilience. You can also increase difficulty by adding weights, slowing down movements, or advancing to more challenging variations.
Build Injury-Resistant Hamstrings
With expert guidance from running biomechanics specialists Drs. Daniel Strauss and Austin Webster, you’ll finally address contributing factors to hamstring tightness and build the mobile, stable, strong posterior chain that supports a lifetime of injury-resistant running.
