Got a lot done in the last two days. I’ve been waking up with a sore lower back on and off for the last couple of months. Nothing serious, just a bit of an ache that goes away pretty soon after getting up. Nevertheless, I was wondering what was causing it, since I hadn’t done myself an injury that I could recall. After doing a bit of reading up on general training I’ve figured it out. Since I’m doing a fair bit of cycling and running, my hip flexors are getting a good workout. They tend to pull my pelvis/lower spine forward, and my abdominals would tend to pull it back. However, I can’t remember the last time I did a sit-up, so my abs are seriously weak and it’s most likely this imbalance which is causing the problem.

This week is the first week back training after the New Year, so I decided to incorporate some ‘core’ work, ie: exercises to strengthen the torso area, back and front. Did them on Monday, got up on Tuesday and did them again, then cycled into work and home again, then went for a 20min run last night. According to the scales this morning I’ve lost 2kg since Monday which gets me back to pre-Christmas weight, though it must be just a loss of water. Anyway, I’ll take it.

B: 15km – R: 3.5km – 2 core sessions
