• The average bench press weight for a male lifter is 98 kg (1RM), and for a female lifter, it is 51 kg (1RM).
• Male beginners should aim to lift 47 kg (1RM), and female beginners should aim to lift 17 kg (1RM).
• According to one Reddit thread, a good starting point for most guys is to aim for 1.5 times their body weight, which is around 225 lbs or 102 kg for a 68 kg person.
• Another Reddit thread suggests that a good target for an average to overweight male is 2 plates on each side or 225 pounds, which is around 102 kg.

Its important to note that these are just general guidelines, and what constitutes a "good" bench press weight can vary widely depending on individual factors. Its also important to focus on proper form and consistency rather than just lifting as much weight as possible.
