Building strength/sore from cycling?

[OakLeaf]

Just do 'em with your hands close in and be sure to keep your scapulae retracted, shoulders in their socket. I learned all that the hard way and I'm still nursing rotator cuff trouble from those pushups (and I only got to 69...)

I don't understand how you could hurt your back doing something isometric like planks? Yeah, if you add hip dips or leg raises, but just plain planks? Care to elaborate?


I'll add another thing that I referenced in another thread - how important it is to maintain the lumbar curve. Cycling and Pilates really tend to accentuate the loss of lumbar lordosis that comes with age. Yoga (for me, with an EXCELLENT Anusara Yoga instructor) is helping me restore that curve.
