Kellan Lutz – Grab Your Sacks!! Gives TV Crew Fabulous Cornhole Prizes

Jacked up Kellan Lutz's biggest muscle might be his heart -- he just hooked up the crew of his new TV show with some serious swag, but he made 'em earn it with an intense pick-up game of cornhole.

We’re told Lutz -- who hosts the new FOX adrenaline junkie show "Bullseye" -- showed up on the last day of shooting and handed out raffle tickets to roughly 100 crew members.

Each person got 3 shots to drop their sack in the hole and win one of the awesome prizes Kellan bought -- including Xboxes, PS4s, iPad Airs, Beats by Dre headphones, 50” TVs, Fitbits and Bluetooth speakers. Total cost to the host (with the most) ... more than $10k, we're told.

The biggest winner of the day might be the craft services woman who scored a 50" Samsung flat screen!

We're told Kellan wanted to thank his co-workers for their hard work shooting the show -- where contestants hurl their bodies (or have it hurled) at a giant bullseye.
