Ask AI: How much would I be able to deadlift if, I weighed 135 lbs and I can do 20 pullups

As an AI, I can't directly predict your deadlift max based on your weight and ability to do 20 pullups. Many different factors can influence how much you can deadlift, including your muscle mass, technique, nutrition and overall health. However, if you can do 20 pullups, this suggests a strong back and arm strength, which is beneficial for deadlifting. Technique is a crucial aspect in deadlifting though, so make sure your form is correct to prevent injuries. You can try starting with a weight that's around 1.5 to 2 times your body weight (about 202.5 to 270 lbs). Then adjust based on how comfortable you are. Always remember it's better to lift a lighter amount with the correct form than a higher weight with wrong form to prevent serious injuries. Consultation with a certified personal trainer or professional can provide more personalized advice.
