Sandy - You probably made the right choice to give it a rest for a few days. IMO, training to the point of being so sore you have to take a break for a couple of days wasn't as beneficial as cutting those kicks in half and picking up your training again the next day and/or the day after.

I remember early on in my MMA training, doing thai style knees to the midsection. My neck was so sore for several days after from my training partners hands cranking on my neck. We should have dropped our training load that day long before we did so we could have picked it back up again the next day. Instead, it was nearly a week before I could train again. Not a very good idea if your training for neural adaptation.

I wouldn't cut back on the training on the count of energy. I would up the carbs some and drop the calories elsewhere if I needed to in order to keep dropping weight. The training is where it's at!
