I did Atkins diet few years back (Atkins + 5 days a week workout in the gym). It lasts for 7 months. I lost 10 kgs. But friends said that I look tired and dry (skin). Now, I still go to gym buy I don't do Atkins. Trainer friend told me that low carbs diet makes us tired and dry. I do eat carbs nowadays but not much.

My main target is to lose weight. I didn't do a lot of weight but 1 hour of cardio and 1 hour of weight (light ones for toning).

I lost 10kgs in the 1st month. And plateu after losing -10 kgs and my weight increase. I gain back 3 kgs with total lost of -7kgs instead. I did the same regime. Never increase or decrease.

Currently, My trainer gave me a lot of cardio exercises. He told me to increase and decrease my speed from time to time instead of fast pace throughout 20-30 min of jog. That is to prevent muscle burning instead of fat. And he told me to use dumbells or body weight for toning instead of machines.

So what should I do? What kind of machine should I use and how?

Body building? No, I don't want bulk muscles:( ... Btw, I'm a female, so weight loss and toning up is what I need
