Good recs on core strengthening. I did a lot of core work and it helped a great deal for life in general. Lot’s of videos out there on core work for cyclists. However, I neglected doing back specific strengthening exercises which resulted in a super strong core (not six pack abs by any stretch of the imagination) but to the detriment of my back muscles which resulted in pain during prolonged standing in my glute region. So now I am doing PT to get my body back in balance. Morale to the story, do core AND back exercises. Another issue is having strong quads (an issue? Seriously? says backwards hat Dylan) which also threw my back out of balance. So my exercise should help with that imbalance as well.
