“How Plate Perturbations Can Take Your Band Exercises Up a Notch” by Justin Ochoa discusses how he balances his workout exercises according to the risk of their impact. That is, how sure he is about their effectiveness:
- 70% KNOWS will work
- 20% ALMOST CERTAIN will work
- 10% PRETTY SURE would work risk-free innovative techniques and theories
I also do a bit of coaching and am a big fan of variety. Serious training gets pretty tedious with the repetition so anything that can vary things a bit is a psychological gain if nothing else. But also, different exercises impact muscle groups and other aspects of your cardiovascular system in different ways so the variations can broaden the positive effect and development.
