Respawn Fitness is perfect for recovery, leveling up, and getting back in the game stronger. Power-Up Training feels like boosting your stats IRL, solid for workouts and nutrition. Level Up Fitness gamifies the whole process of getting fit. XP Gains plays on experience points and muscle gains, clean and catchy. Code & Grind ties fitness into the dev and gamer grind mindset. Endgame Athletics sounds badass, like training for the final boss battle. Meta Physique is a play on metagame and physique, ideal for those who think strategy even in fitness. AFK Training because you gotta get off the chair sometimes to level up IRL. Would definitely check out a program with any of these names if it had the right branding and vibe.
