Frequently Asked Questions
When should I rebirth in +1 Muscle to Arm Wrestle?
You should rebirth when your current muscle exceeds the break-even threshold — the point where the multiplier gain from rebirth offsets the muscle you lose. This calculator helps you find that exact point.
What do rebirth multipliers do?
Rebirth multipliers increase your muscle per step and wins per match. Higher rebirth levels give bigger multipliers but cost exponentially more muscle to reach.
Do I lose all my muscle when I rebirth?
Yes, rebirth resets your muscle to zero, but you gain permanent multipliers that make regaining muscle much faster. The key is rebirthing at the right time for maximum efficiency.
