"I'll just have to crush you with pure power!" Gerben realised, activating his explosive muscle fibres.
As he did this, his ligaments grew stronger but primarily, his muscles grew larger by a significant amount. Now, he looked akin to a full-on bodybuilder. Since his fat mass remained the same, his body fat percentage was actively decreasing and making him seem more vascular by the second.

"I'll prove my strength!" Gerben said, as his eyes became bloodshot with his heightened blood flow.
He ran ahead, with superhuman speed, and stopped the burly zombie right in its tracks by slamming his shin right into its gut. The zombie curled over in reaction and even with its amplified durability, this kick snapped one of its ribs.
The crazed zombie still ran right back to him, seemingly unaffected by its injury .
