Hi, it's me again.

Just wonder, for free weight bench, if I use lighter weights but do more reps is this the same as doing the max weight I can do? I don't have a spot at home and I don't want to kill myself. It feels safer with lower weights too.

 

I would do lower weights as well without a spotter. Never go balls to the ball without one. You can make some size with high reps. Usually high reps are associated with getting cut.
