I have been lurking in the S&C forum for a while and taking in the great info here. I am training for World Championships in July and have adopted a couple of the training routines to go along with my regular training and cardio and weight regimens. I added Taku's HIIT, the Tabata Thrusters and front squats and the Team Quest Dumbell Complexes simply because these are what I can do with what I have access to. My question is, as I do the Team Quest Complexes and the Tabata routines, my shoulders and legs get a great burn for a couple days but it messes with my weight workout because I am hesitant to do shoulders and legs when I am sore there because I don't think I have ample amount of recuperative time for them. I train 2-3 times a day besides my job and family and think it's a necessity to do sprint interval and fast twitch resistance training every day since July is coming up. Any suggestions on balancing these cardio sets with weight training?
