30%

Explanation:

What is the percentage of improvement for a client who has a baseline 10RM of 50 lb (22.7 kg) on the bench press and improves to 65 lb (29.5 kg) at her follow-up test session 3 months later.

Percentage improvement is given by the following steps:

First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase : Original Number * 100.

Therefore percentage improvement = [ (65 lb - 50 lb) / 50 lb] x 100 = 30%
