I'm doing Brian Alsruhes linear progression program and it calls for using ramping weights.
Problem is everywhere I've looked for help with programming it uses very high weight for an example.

My stats are
Squat: 25 lbs (skipped too many leg days when starting out)
Deadlift:50 lbs
Bench:60 lbs
OHP: 25 lbs

Any help with where I should start with the ramp? I always go either too light or way too heavy from the start.
