Went to boxing on Monday for the first time, marking the start of a 4-day boxing gym week.

First drill was forming 2 lines and going down the length of the gym throwing a right and then a left to the body, followed by a couple of other combos that the coach called out.

Partnered up afterwards and Coach Tommy worked with me since everyone else picked each other very quickly. Main drill was a right-hand lead, post with the right, then a left hook to the body and left to the face. Took me awhile to realize you're quickly replacing the post arm with the left, not holding them with the post and throwing the hook at the same time, but it soon clicked and I was moving at angles better as a result of not being pinned with my right arm. 

Once we moved onto other combos I realized I was tensing up and actively fought against that. I definitely do it more when working with a coach vs a regular partner. Sinuses also started impacting my breathing when they seemed to have gotten better last week.

Great session overall. I think Coach Tommy is brothers with Tuesday's coach; they look like twins.

Glute held up fine. I just made sure not to do high knees when skipping rope, which we usually do in the last 30 seconds of a round to burnout.

Unfortunately, woke up with my back feeling stiff, and when warming up breakfast in the morning my left side suddenly seized up. Luckily it's more in the lat area, not lower back. Bobbing and weaving, while feeling fine in the moment, do seem to make my back act up later that day and the next morning. Quite possible my mattress is a factor in that, as well.
