I train tuesday to sat with my new routine. My muscles are sore when I flex them, no tendon or joint pain. After laying off Sun and Mon I'm fully recovered and craving that muscle stimulation again, I've never felt so positive before. These quick routines of high intensity with as of as many sets I can fit in the time limit of 5 mins is giving me noticeable results. I never realised I could bang out a decent amount of reps again after 5 seconds rest, I've always gone with the norm of resting 30 secs or more, my cardio is improving this way too!
