Percents relate to your one rep max or 1RM. Similarly, 5RM is your 5 rep max - the weight you can lift for 5 straight repetitions but feel you would fail rep 6.
I got to this thread by using the new "Most Discussed Topics" option, and failed to realize you posted in beginners forum. I didn't mean to confuse you with that notation, I assumed you were alredy familiar with programs here.
The basic point, however, remains. You need to pick up a structured program and follow it. Many have done well on Chad Waterbury's programs, but common trait of all successuful programs is hard work on big compound lifts (Squats, Deadlifts, Benches, Rows, Pull-ups, Overhead Presses). You can supplement that with bodyweight work, if you wish and feel you can handle it. Also, be sure to check Vroom's Beginner Threads (I and II).
