Centurion, tibilicus and GC, thanks so much for your input.

You need a bench to do a bench press, so i wouldnt recommend doing it without a bench otherwise you will injure yourself. SFTS mentioned cleans i believe which is an excellent workout that builds up your explosive ability in sports. You only need a bar and plates for this.
What is "cleans" ?

My budget can max out at 750$, fyi.

SFTS, please do. Especially the tools I need to acquire precisely.
