At RFC, we used to do "anaerobic footwork" patterns twice weekly. The idea was to do these as fast as possible - obviously, you can't let the technique go to hell, but quality of execution matters less than power output. If you hit the end of the strip, turn around.
- ( 10 sec. Advances, 20 sec. Rest ) x 5
- ( 10 sec. Retreats, 20 sec. Rest ) x 5
- ( 20 sec. Advance/Retreat between the en-garde lines, 40 sec rest ) x 5
- ( 1 min. Advance-Lunge, Recover Back, Retreat-Lunge, Recover Fwd, 1 min rest ) x 3
The whole sequence was done twice through, with a 2 minute break in between.
Experiment with the pattern, but as you can see, the more intense exercises are shorter; the longer patterns are less taxing because they use the same muscles less frequently.
It's one heck of a physical/mental exercise, trying to keep your technique together through fatigue. Done regularly (and take deloading weeks!!!), it's quite effective, and gives teenage foilists a set part of practice to whine about.
