"It is vain to do with more what can be done with less."- William of Occam
In other words: Whatever the endeavor, don't make it more complicated than it has to be.
Let's examine this in context of training.
The RKC Program Minimum:
Get-ups and swings.
Variety doe not mean complexity.
There are TONS of ways to put this together, aside from the "do each exercise 2 days per week" as outlined in the Enter the Kettlebell book.
Swings :30 on, 1:00 off for 5 rounds.
swings :30 on, :30 off for 10:00
If you don't think there is a HUGE amount of difference between those two workouts, you haven't tried them.
What if you don't have a kettlebell?
How about a bodyweight version of the Program Minimum?
Burpee (Squat thrust) and pullup.
I like these two exercises because they hit every angle.
Here is a starting point:
Burpee :30 on, 1:00 off for 6 rounds.
Try it. Simple and brutal.
