I am a Catheite-- and an Intensity Junkie, and I was doing the Cathe IS series right before I ordered Slim Series..
My thoughts:
I really like these! Yes-- it's a tad repetitive if I were to do them only the slim series for 4- 6 weeks, but hey, I have done Cathe rotations for that long, and threw a Powerstrike in here and there to break up the monotony-- (by the way, when I say monotony, I am referring to the pre IS days, because there are so many great options on the IS series!)
Back to the Slim series, as stated before, they are low weight, hi rep, and the speed of the exercises keeps my heart rate elevated -- a little bit of cardio is thrown in between the weight work, but if you are a Cathe addict, it will be relatively easy to get thru it-- easy, but not in effective.
I have done these tapes for the past week, havent noticed any major changes, but I am going away for a few days tomorrow, and I will be exercise free, but will pick them up when I get back and start a four week rotation with the slim series. and I have every intention of throwing a Cathe interval cardio + a powerstrike in there as well-- gotta have that steady state cardio, or my body dosent behave the right way!
They have been providing a nice break from all the Cathe tapes, because some days I want a long thorough workout, without all the impact, yet I think they can be just as intense. I feel they are "what you put into it" kind of workouts.
Get em. Cant beat the price. and if you dont like them, heck, everyone wants to swap for these!
and the tapes have some great floorwork in them, which for me is a big plus, as I feel so many tapes these days are being produced, omitting those particular kind of exercises.
Minimal equpiment, a big plus as well.
If only I can get myself out of the "if I dont do a cathe tape, I am not REALLY working hard enough" mindset, all should be ok.
