Below is a link to a well written Manolo Mendez article articulating his position why a horse should be ridden in a supple and tension free way. He articulates his case from a biomechanical viewpoint using non-technical terms and illustrative examples to tie classical principals to biomechanics. He also provides general training tips, an exercise to assess balance and suppleness and discusses what he looks for in the way horses travel and carry themselves in determining the quality of the work.
The article does a good job balancing removing jargon while still having substance.
