This depends on your gender, body weight, and training level. Some general guidelines for males are 1-1.2 x bodyweight for a beginner, 2-3 x bodyweight for intermediate, up to 5 x bodyweight for very elite lifters. These generalized numbers for females are 0.6-1 x bodyweight for beginners, 2-3 x for intermediate, and 4 x for elite athletes. Some examples:  200 lb. male: Beginner = 250 lb.; Intermediate = 550 lb.; Elite = 1000 lb. 170 lb. female: Beginner = 120 lb.; Intermediate = 350 lb.; Elite = 700 lb.
