Expend a CS die (sometimes called straining or pushing yourself) this is recovered when you have an opportunity to relax and shake it off not necessarily a long time. Your CS based action is more effective than the CS dice than you spend. I spent only one CS die but it gave me 3 die of effect.
In effect by having a heroic exertion rule maneuvers don't need to be categorized as encounter powers (they just need higher cs die costs) or any such thing those using the rule will have fighters with climactic abilities. One noted benefit is that it has a discouragement for hitting with your biggest mojo at the beginning of the fight since the strain makes you less effective subsequently.
Similar to Heroic exertion above except HD might be spent for a similar purpose or specific moves may be designated as requiring the HD independent of their CS cost. (suggested I think by CarlT.)
Climactic moves can only be accessed when you are on the ropes such as below 50 percent hit points these may be more erratic and more powerful (having reduced chance to hit but doing more damage or actually having more extreme effects or effects that involve rolling on a table making them unpredictable)
Changing the fighter to Encounter Based CS
No I don't mean multiplying the number of dice you get (this might work better) Use the above rules plus one more.
It's easy to assume and see how one might be disinclined to exert early because of the penalty but what if Desperation moves were also available after all CS dice are expended? ... then desperation becomes the culmination of the fight and using the big booms even when you get a temporary reduction in capability is tempting. (need to ward against this becoming the only gambit - ie careful calibration so desperation moves aren't too useful)

"Wizards and Warriors need abilities with explicit effects for opposite reasons. With the wizard its because you need to create artificial limits on them, they have no natural ones and for the Warrior you need to grant permission to do awesome."
