I am almost finished with my degree in Exercise Science and Health Promotion and have dealt with this. You said you are taking 175g of protein a day? Well that is not always good because the excess protein you body takes in, above the normal range, will just be converted and stored as fat or released through urine. I would recommend that you tone down on your doses of protein and more importantly take your protein supplement immediately after you get done lifting. For example, after I get done lifting I take 20 grams of 100% Whey Protein mixed with milk. This gives me calcium and an extra kick of protein and helps not convert it to fat. You have to remember that you won't see results in months, it can take longer depending on your body type and genetics. For me it took me 4 years to put on 35 pounds of healthy muscle, but that can be different for everyone. For your weight training technique I would do 35 mins to an hour of cardio most days of the week and keep within your target heart rate. From there I would train your each muscle group either once or twice a week. For example one week I do chest, triceps, and back on Monday and Friday and do biceps, forearms, and shoulders on Wednesday. Then I switch up the exercise the next week. This provided me with important rest for my muscle groups and I could see more gains that way. If you want strength and bulk then due 5-8 repetitions 3-5 sets on each muscle group. It is important to change up the types of lifts every once in a while with each muscle group so you won't hit a plateau. I hope this helps you, like I said just be patient and you should see the results in time.
