My workout - question about weights and bulking up

Hi! So I workout around 4-5 days per week. I do 30-45 min of cardio (either 1 min sprint, 1 min walk on a treadmill or the same on a bike with 1 min high resistance, high speed then 1 min low resistance/speed). Then I do weight training with 10lb weights - squats, lunges, hammer curls, shoulder presses etc. I haven't lifted for a very long time and just recently got into it again (around earlier February), hence the light weights.
I need to lose around 10-20 lbs (I'm 150 right now aiming for around 135ish, 5'11" and a girl). I also eat very clean usually!

Is this a good workout for fat loss? And I've heard different things about bulking up so that may be a silly question but will I bulk up or no?

Thank you! I really appreciate it

Bulking up only happens if you're following a specialized training plan designed solely for that purpose (see hypertrophy training) while eating at a surplus. Even then it's not a whole lot for women because it takes testosterone. If you're eating at a deficit the only gains you will see in size are as a result of "noob gains." Basically whenever you first start any sort of high intensity lifting regimen your body will adapt to it by giving a very slight increase in muscle mass. Once the body adapts (which only takes a few training sessions for some people and a few months for others) that stops. Beyond that you won't see any mass gains without training and eating specifically for it.

Honestly you're not going to see a whole lot of progress with a regimen like that. You need to be working with much heavier weights for much lower reps and focusing more on compound movements. If you look up on the internet you will see there are a ton of beginner oriented heavy weightlifting programs ranging from Stronglifts to GSLP to Starting Strength to Madcow and then some. Read a bit up on these before you decide which one you want to go with and then do it. Now its important to note that regardless of which one you choose you should read the book for Starting Strength from cover to cover because there is a lot of information about the background science behind just how lifting works that you NEED to know if you want to get the most out of these programs. Just be sure to throw the dietary recommendations they state in there totally out the window if you're not looking to bulk.

You won't gain muscle on a deficit of calories.
