I have a American book on everyday stretches in the office..

• diff: availability of teachers and classes
• Diff: breathing is central to many if not all yoga practices
• Diff: In terms of goal, yoga is NOT so focused on reaching a particular range of motion. For me, I don’t aim at that at all, though I may achieve that as a by-product.
• Diff: hard stretch for athletes and dancers often feel like painful tortures. I now believe yoga should NEVER feel torturous. You need effort, not brute force willpower.
