stick to just twice a week, I dont mean to sound disrespectful but if you are squating 45kg for 4x10 your only a beginner and have a long way to go and to progress to hit big numbers.

Stick to your basic routine keep it short and abbreviated.
Personally I would go with
Squat 3-4 sets x5-8 reps
Bench Press, same
Pull ups or Pull down 2x8-10
Ab work.

thats it nice and basic, sets and reps don't include warm ups.
If you wanted every 3rd or 4th session you could do deadlifts instead of squats and an overhead press instead of benchpress.
Just aim to add a little weight to the bar each week or more reps, you can still get from some places fractunal weight plates 1/4 and 1/5 kg weight plates some 1/2 kg or 1kg junps can be made from week to week.
