How do I make my squats safer? I dont have a power rack to support the barbell in case I won't be able to finish the rep. I was able to increase my weight by 5 kilos by using just dumbbells and barbells. So far the weight that I squat when using the barbell is manageable about 50lbs since Im still a beginner hehe. And when I do squats I first imitate a deadlift stance; carry the barbell up to my shoulders then do a semi shoulder press and place it on my back.

I do a full body workout three times a week. I don't take supplements; what I do is I eat a lot of eggs and meat but I am planning to buy whey for more protein intake. What whey should I get and how much is it? Where can I buy a power rack?

Also, how do I make my chest bigger since it is lagging behind? Should I do more chest workouts? I usually do push ups; about 13 reps three sets; I do have a bench but I need to clean it up hehe i can probably do regular bench press and incline but my concern is the decline, is it necessary to do decline bench press? How do you form a good looking chest?

Also about our food intake; how do we track our food intake? Its hard to find a guide regarding this since our food is different from americans.

I only do 1 workout per muscle; the range would be 8 reps- 3 sets. I am gradually increasing the weight that I carry since im tracking them. Thank you for responding

Buy an olympic barbell with Rubber bumper plates that you can throw around.
