One thing I noticed, the less tired and the more energized I am before working out, the more intense my workout becomes because I get tired much later. I accidentally hit on this that seems to work for me. I eat an oatmeal with nuts and fruits in it from Starbucks a little more than an hour before working out. This gives me an energy kick wave that I ride as hard as I can in workout.
On Monday I stepped up the weight lifting. Three sets, more weight. I am in serious pain today, but fortunately all the right places hurt. Thankfully, my elbows don't hurt, which means my body is getting used to the stress.
