Cross training workouts can be applied in several different ways:
Using a variety of cardiorespiratory equipment within one workout, e.g., ten minutes on the cycle, ten minutes on the treadmill, ten minutes on the stairclimber.
Using a variety of equipment (or modalites) throughout the week, e.g., Monday: run 30 minutes; Wednesday: cycle 40 minutes; Friday: cross-country ski 25 minutes; Saturday: play singles tennis for one hour.
Periodlizing cross-training involves the use of different modalities across large blocks of time or seasons, e.g., summber: emphasize swimming and training for windsurfing; fall: versa-climber, outdoor rock-climing and tennis; winter: cross-country and downhill skiing; spring: running and canoeing.
