High Rep Low weight Problem!!

I've been lifting with low amounts of weight (don't do any exercise with any thing above 145lbs. I mostly bench between 90lbs to 100lbs,I curl with 50lbs and I only squat 130 at the most!) Itry to do anywhere from 15 to 30 reps,but no less than 12 on any exercise.I weight 270, I'm 30% bodyfat and I'm trying to get to lose the weight not have fat over muscle ,so I don't lift alot of weight, Plus I'm still working on my form, since I've only been lifting for 3 months with consistancy So my question is should I

1)Increase the weight I lift gradually,and decrease my reps?? a) How many Reps should I do??

2)USE EVEN LESS WEIGHT IN MY WORKOUT??

Please Help!!

There's alot more to it than just how much you lift - like how often are you lifting and what your eating habits are. I'd personally go for higher weight and lower reps.

I vote for number 1. Target sets in the 6-10 rep range.

Using heavy weights won't make you fatter. Too much food will.

Numero uno! About the rep range, there's many voices out there, some say use heavy weights to do 4-6, others say up to 8, 10 or 12. Hmm... it's a maze. In my workout i do heavy weights,many sets,low reps, but i'm after strength, not volume.

15-30 reps is only going to help with endurance. No build muscle or strength.

Aim for about 10 reps. Maybe less.

Use more weight.
