Hi Kali. Are you sure you can handle 5-6 cardios a week? If those are long cardios you might be overtraining. Of course that depends on the person because I know people here that can do that easily. I have the same problem with bulky thighs (and lower body). I keep posting threads whining about it. But a couple of months ago I changed my usual routine which was 5-6 high intensity short cardios a week followed by training my body parts twice a week. Not that I got bad results, but that wasn't doing anything with my bulky thighs. At the moment I'm doing at least 3 long (at least an hour) high intensity cardios a week and 3 weight training workouts a week -with weights, the heaviest I can handle- (one full body and two splits PLB one day and PUB another day, or sometimes 3 full body, or sometimes different body parts 3 times a week e.g. with PS). The days I weight train if I feel like it I add 1 short cardio (about 30 mins) after weight training.
That is working wonders for my lower body I have to say. The first two weeks I didn't see any noticeable results, but after week 3 my thighs started shrinking. This is my week 8 and some of my pants are starting to look loose (in a couple of weeks I know I'm gonna have to buy some new pants). Diet is also important. I decreased my added sugar intake to 50g or less a day (although some days cheating is inevitable), along with my usual high fiber, high protein, low fat, mostly organic diet. The key is to have separate days where you do intense cardio only (maybe you can add some abs, but no weight training on those days), have days where you weight train (with weights and don't be scared about this) and maybe add some short cardios after that, diet and patience (because you don't get bulky in a day and you can't expect to get rid of it in a day either). However, every once in a while you have to change your rotations, maybe do short cardios and more weight training for a couple of weeks and then go back to long cardios again.I hope this helps. Take care.
