When used, a light blue circle shrinks to fill a smaller red one. With a second button press when the two circles meet, Wii Fit Trainer is healed for 2% and receives various buffs for 9.8 seconds in Smash 4 and 12.2 seconds in Ultimate (alternatively, down special can be held and released to activate Deep Breathing). The move has a 60 second refresh time in Smash 4, which was reduced to 40 seconds in Ultimate. The refresh timer starts immediately when the move is successfully activated, failed, or canceled through shielding or airdodging. If Deep Breathing is used again before it is refreshed, it will take longer to activate successfully. A stale Deep Breathing will yield smaller buffs and a shorter active time (as short as 7.2 seconds in Smash 4 and ~8.8 seconds in Ultimate). Deep Breathing will always be refreshed when Wii Fit Trainer loses a stock. If the move is used while Deep Breathing is already active, the original Deep Breathing effects are canceled.
In Smash 4, Deep Breathing offered only a few stat buffs. In Ultimate, the move's effects were greatly expanded, affecting almost every aspect of Wii Fit Trainer's mobility. The extent to which Deep Breathing buffs Wii Fit Trainer depends on how fresh or stale the move is. On the chart, the values on the left result from the stalest possible Deep Breathing activation, while the values on the right result from a completely fresh use.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
The deep breathing technique is a common one used in yoga to soothe and calm a performer down. The circles that appear reflect the circles used in Wii Fit's yoga exercises, where they serve as a visual guide for inhaling and exhaling during the exercises.
