26 speed‑day accessories
Gerry DeFilippo dropped a demo reel of 26 speed‑day accessory moves — pistol squats, Bulgarian split squats, GHR hamstring isos and more — aimed at fast‑twitch development and unilateral strength work (x.com). Social threads around the reel reinforced training basics: progressive overload, tight mind‑muscle connection, 60–90s rests for hypertrophy, and pairing sessions with a protein surplus ( ).
Gerry DeFilippo is the owner and head trainer of Challenger Strength and programs organizations including the Jersey Hitmen, Gamers Baseball Academy, New Jersey City University (NJCU) and Caldwell University. (challengerstrength.com) Challenger Strength’s YouTube channel lists roughly 192 videos and shows a short titled “Preview of the NEW OnlyStrength!” uploaded January 23, 2026, indicating an app/product rollout tied to his content. (youtube.com) His TikTok presence includes about 38,000 followers and 1.5 million total likes, and individual speed/acceleration videos on that account have attracted thousands of engagements. (tiktok.com) DeFilippo has repeatedly published long accessory compilations across platforms — a TikTok titled “33 of my fav lower body accessories” that drew hundreds of likes and a Facebook reel listing “23 of my favorite hamstring exercises.” (tiktok.com) Challenger Strength lists in-person programming and facility expansion to Kenilworth and Berkeley Heights, New Jersey, and DeFilippo’s bio credits him with four USPHL NCDC Founders Cup regular-season championships and two Dineen Cup championships since 2016. (challengerstrength.com) The 26-move reel follows that pattern of platform-specific accessory catalogs and aligns with the broader OnlyStrength preview and ongoing Challenger Strength programming efforts.
