She is stuck at 135 lbs. and we are trying to figure out if upping her cardio is the answer. Are her cals too low? Is she overtraining? Should she cut her cals further? More cardio? Time for some Clen or Anavar? Any input would be helpful.

What are the goals? To lose body fat or put on muscle?? Definitely not time for clen/var after only six months of training...

She wants to lose more bf. with as little muscle loss as possible.

If that's been her diet and training for 8 months straight, she definitely needs to change it...Switch up her split...for example: Monday - chest/shoulders...Tuesday - biceps/triceps...Thursdays - back/traps...Friday - legs...have her do 30-45 minutes of cardio on the days with weights, then maybe 45-60 minutes of cardio two other days (for example, Wednesday/Saturday). Make it of higher intensity. Have her eating 5-6 meals a day instead of just 4. Maybe cut back on the cheat day. Sure, it helps keep cravings under control, but she could be blowing a week's worth of work...instead of a cheat DAY, have it be a cheat MEAL.

I've been a personal trainer for several years now and have had a chance to work with many people. Over the years you see what works best on people and what doesn't. I've noticed that if a female is already at a healthy bodyfat percentage and weight that a fairly strict diet needs to be followed to further drop bodyfat. Six meals a day is going to be a must, any less than that makes lossing fat difficult. Personally when I diet down for a show i am eating 8-9 meals a day every 2 hours. As for the six meals they should consist of higher amounts of lean protein to help retain the muscle mass and the carbs should be very low glycemic carbs. That means ditching the cereal, oatmeal and brown rice. Those will be good souces of carbs to maintain muscle but they will make it very difficult to lose bodyfat. The carbs yu should focus on would ideally be veggies, so for example Meal 1 could be 1 whole egg with 4 egg whites all scambled with 1-2 cups of broccoli. Meal 2 could be a chichen salad consisting of half a chicken breast with 1-2 cups of spinach and broccoli. Meal 3 for example could be 1 can of tuna with a small apple. The only veggies to stay away from would be carrots and corn they are too starchy. Fruits are fine too just make sure they are not tropical frits such as bananas. This is a very strict diet but i guarentee you it will work. Now since see is twenty I would run this diet strictly during the weekdays when you can stick to it and have two cheat days on the weekends. Afterall if you go out to clubs or go party and hang out with friends on the weekends the chances of you being able to eat very strictly are going to be very difficult. So why not make those your high carb cheat days. Those days I would still eat 6 maels a day just add dense carbs to each meal such as oatmeal, gritts, brown rice. As far as the training and cardio goes I think it is fine manybe even cut back a little on the cardio. The diet is going to be the biggest factor in determining bodyfat lose so concentrate on that. Just also make such you lift very heavy, that will help you retain the muscle you have. By heavy I mean your working sets should be no more than 12 reps to failure. If you can put that weight up more than 12 times with good for its too light. Hope that helps
