Hi guys.

I have some questions to ask here.

My background; Im very new to gym-like joined them a week ago and Im a girl.

My goal: to lose weight and I don't want to lose my muscle, most of my girlfriend lose weight but their skin quite flabby

I started my weight loss journey last months and hit plateau for 2 weeks because what I have been doing only control my portion and brisk walking. Then I discover that, I might loss a muscle since I focused too much on brisk walking. That is when I decided to join the gym.

So, at the gym, I lift dumb bell and use all the machine with the black plate weight 5kg each. Im not sure their name but here is the machine description:

(this is the machine function)
1. I sit in the chair n lift the weight using my calf/feet
2. I have to lift weight using my stomach by bending my body to the front
3. I lay down and use my calf/back to lift the weight(I heard it focus on hamstring)
4. I have to pull the weight to my body and push it back
5. I have to pull the bar from the top to my stomach and release it back to the top

So for all this machine and dumb bell(I lift 2.5kg each)-my routine is to do 12reps and 4 sets in one round(my plate is 15kg for upper body/machine that use hand strength, but for those using leg, im doing 10kg and 15kg)-taking break for about 30 seconds after each set

After that, I do cardio-jog, run, brisk walking on treadmill for 20 minutes; before repeat those thing above.

Total cardio/daily: 40-50minutes(2-3 sets;20 minutes each)
Total training with machine: 12reps(4 set)-in one round; will do 2 rounds everyday

Doing squat without weight-50(10 reps in one go)

My question:
1. Am I doing it right(on sets and reps?)as I want to keep my muscle and at the same time losing my body fat?Or my reps n sets is too little?

2. Im doing atkins whereby my calorie intake is between 1,200 daily(protein range 70-90gm), but I heard I have to eat more protein since I workout more than 1 hour every day. So, should I increase my protein intake?(I just want to be careful to not interrupting my diet)

3. Im not rushing in losing weight, 1-2kg is my weekly goals. But I want to do it right(not yoyo diet and want to have active lifestyle)

4. Im taking probiotic, multivitamin, omega oil and BCAA for my supplements. I just bought BCAA-2-3 days ago as I read it is good in keeping the muscle.

Thanks and sorry since im totally noob🙇🏻‍♀️

Thanks for the motivation
I have sore muscle after 2 days join gym and has to stop doing squat for 2 days after start doing it. I see, will finish BCAA and focus more on eating a good food. I enjoy doing atkins because I don't have carb craving. I don't eat rice and bread, all food with santan is not my favourite as well.

So far, I feel good doing those reps, maybe will slow down during my rest day.

One more question if you are free to enlighten me
I read about arm day, leg day where they focus on 1 muscle group every two days at gym and as for now Im doing all exercise for whole group of muscle in my body daily. Should I continue with my routine or focus on arm in one day and leg on the other day?
