I'm Gerry DeFilippo (@Challenger_ST), a strength and speed coach with more than 15 years of experience helping athletes become faster, stronger, and more explosive. On X, I share daily, actionable content, including quick drill demonstration videos, form tips, workout programming ideas, training app breakdowns, and real athlete progress updates. My posts focus on practical, no-fluff advice that delivers measurable results for sports performance.
My audience consists primarily of high school and college athletes—especially those in football, baseball, and track and field—along with strength coaches and serious gym-goers aged 15–35. Most are in the United States and are actively training to improve speed, power, agility, and overall athleticism for tryouts, upcoming seasons, or personal bests. They engage heavily with bookmarkable content.

FAQ
Who is your audience?
My audience consists primarily of high school and college athletes (especially in football, baseball, and track & field), strength & speed coaches, and serious gym-goers aged 15–35.
Most are based in the United States and are actively training to improve speed, explosiveness, strength, agility, and overall athletic performance for tryouts, upcoming seasons, or personal bests.
They engage heavily with practical, no-fluff content: short drill demonstration videos, form tips, workout programming, and training app breakdowns.
My recent analytics show strong bookmark growth (people saving tips for later), high impressions, and solid engagement from this motivated, results-driven group.
This audience is ideal for brands offering training gear, supplements, recovery tools, cleats, or performance apps.
What brands have you worked with?
I am currently building my portfolio of paid brand collaborations on Collabstr and am actively open to new partnerships.
I have previously promoted my own 7-day training app trial and consistently create authentic content around strength, speed, and athletic development.
I prioritize genuine integrations that add real value to my audience (practical tips, drills, or honest reviews) rather than hard sells.
Happy to discuss custom campaigns with brands in fitness, sports performance, supplements, training equipment, recovery, or athletic apparel. My 90K X followers + 1.3% engagement rate in a highly targeted niche make me a strong fit for authentic promotions.
