The cardio targeting the same muscle groups is great cause you basically double up on the work out and while working your cardio still burn those muscles a little again to force more growth and on top of that the high intensity/low weight exercise of the same muscles will help you recover a lot faster and spare you at least 50% of the soreness the next day cause you're not stressing them too much but still getting that blood pump going! It's a very intensive program though and in order to not over train and burn yourself out, I suggest if there are people that want to stick to it, don't do it back to back! take a 1 or better yet 2 week break, with a less intensive program of 3-4 days a week (still lift heavy though) but make sure you rest 3 or 4 days out of the week before you start another round of MFT28. another suggestion, for the ones that really want to stick to MFT28 year round... Do the full program, then skip the morning mass building and just do the evening cardio workout for 1 or 2 weeks before going to WAR again. Instead of the London bridges u can use the smith machine, hang under the bar just high enough so there's like 20 inches of space from the ground to your shoulders, then pull yourself up up with one arm, lower and switch to your other arm 10 reps each arm and your good. It will give you an even better burn and it will give your abs a sweet burn too. Keep your body straight (plank) throughout the exercise!!!! About using the smith machine for squats.... I agree with you. Everyone should do REAL squats, however the way Greg does it works for "this" program, cause with all the exercises you do with his leg day workout he pretty much isolates each muscle of your legs and works them hard for 3 sets to failure. If you do REAL squats and lift heavy you'll never be able to do that much reps and sets to work all those muscle groups and get the same kind of burn and definition, so to really get the most out of your leg workouts you should do both REAL heavy lifting and isolation work like in Greg's program. So I'm sticking to Greg's program but I added my own variation of the 5x5 Stronglift program as well, which you do 3x a week (Monday, Wednesday, Friday) but because of Greg's leg day i leave Friday out and lift heavy (420Lbs) on Monday and Wednesday before i start Greg's workout and it's really working for me! Oh and PLEASE PLEASEEEEEE!!!! Do not use the same HORRIBLE deadlift form as Greg! He should get slapped for that! Lol....
