I don't know that there is. Sounds to me like your weight has gone up too quickly for your strength to keep up. Is that 30-40 pound increase predominately fat?
If I gain 5-10 pounds....my reps on chins go down. You can try doing an all out set this week...and add one rep a week onto your chins. I don't care if that last rep is balls to the wall AND you have to have a spot on them...add one rep a week...till you are at your desired goal.
From there...back down to about a set of 6 or so...then start again.
