A low impact series could include separate workouts focussing on, for example, yoga for athletes, without too much of a spiritual component and rock music rather than cymbals and drums, etc; it could include a long DVD with a graduated plan to master pilates moves, kind of a grow-with-us type approach that would last us forever, pilates would totally complement the very high intensity work cathe usually offers by reminding people to think of form and function, body alignment, injury prevention and that every day should not be lived at the same level of intensity; the series could include a couple of kettlebell workouts, one as a circuit (see Paul Katami), another more as a skills clinic and strength/cardio focus. Kettlebells suit low impact exercise fabulously. The series could also include a low impact circuit that does not use the step, or that does use the step but the cardio segments are all taught blast-style.
Some ideas to make low impact into a series and not just a few, token low impact segments dotted here and there hat fans have to cobble together to make a workout.
Thanks.
