This morning, I did FOCUS T25 Gamma Core Speed (176 cal). This is an extra workout available for FOCUS T25. I purchased it to help round out the workout plan that I made. Core Speed's structure is the same as Speed 3.0. It is very fast-paced, and I did have trouble coordinating a few moves. I'm not sure that I thought it was more core-focused than Speed 3.0, but it was fine.
After Core Speed, I did Asylum Vol. 2 Pure Contact. This has some plyo work that I think is useful. Overall, I burned about 285 calories and got a good sweat going.
