Hi Robin
I am an ecto so it's hard for me to build muscle. I have tried lifting weights two ways:
(1) heavy lifting and one body part per week and (2) doing a total body workout 2-3 times a week.
Lifting heavy definitely got my legs into top condition (lean with no cellulite), blasted away a lot of body fat, and I got strong.
When I lifted 2-3 times/week with total body workouts, I got a lot of definition, esp. in the upper body. I also added interval cardio 2-3 times/week, and I was able to burn a lot of extra fat around the middle. Yeah!
So to make this not so long...I really liked the results I got from doing total body workouts 2-3 times week - with interval cardio added of course. I rotated a lot of different tapes so I didn't get bored. I think I did a maximum of 3 days of cardio per week. I think when you're an ecto you need make sure you don't too much cardio because you can actually hinder muscular gains. Everyone is different though so you'll have to experiment. I think one thing that made this rotation so successful is that I didn't restrict myself to a certain rotation of specific tapes. I just followed something like this and did tapes that fell into that category:
Mon-total body weights
Tue-cardio
Wen-total body weights
Thr-cardio
Fri-total body weights
Sat-rest or walk
Sun-rest or walk
Week 2:
Mon-cardio
Tue-total body weights
Wen-cardio
Thr-total body weights
Fri-cardio
Sat-rest or walk
Sun-rest or walk
Total body tapes included: Firm Vol 2, Power Hour, MIS, Weights First, Core First, etc...
Cardio tapes: Intense Moves, Imax, Firm Power Cardio, CTX cardio, MIC, Circuit Max
For cardio, I tried to make sure I didn't do the same type every day. One day I would do step, next day hi/lo, next time kickbox, etc...I also varied intensity. Not having to stick to any particular tapes made the rotation so much more fun. And I think it kept my body guessing a lot. I think that's why I saw good results with this rotation.
I guess this wasn't so short after all. HTH
