Do your core strengthening workouts, or else!

That's just what my physical therapist said.  I'm sitting and doing different exercises at home now and hopefully that will get me back up to speed.  I feel pretty silly now knowing just how easy (relatively) it would have been to just do this on my own before. 

Aside from simply having a weak core, part of my problem was also doing very little trainer riding over the winter and then as soon as it got nice outside I was pounding out the miles and being bent over for a couple hours on end.  That combined with one of my shifters being a little higher on my bars than the other was twisting my back just a little and may have also contributed to the problem. 

So I'm doing some different types of bridging, pelvic tilting, and planks as well as a couple other things every other day.  it takes me about 20 minutes each time.  I can tell I'm getting a workout 'cause my abs are tired afterward and I can feel it a bit the next day.  Let's hope it all helps.  I wanna ride without back spasms and pain afterward, darnit.

Also it should be noted that many people's core deficiencies are actually more of imbalances.  Often people will train their abs but rarely do they train their lower back.  This can cause imbalances in their core and result in injuries or problems in the future.
