Explanation:

• Question 7: Current body composition directly relates to muscle mass. Higher muscle mass is a part of body composition, so this factor impacts muscle growth.
• Question 8: Age and hormones are affected by age growth. As age increases, hormonal changes (e.g., decline in testosterone in males over time) impact muscle growth.
• Question 9: Sex (gender) is a factor. Males generally have higher testosterone levels (a hormone that aids muscle growth) compared to females, so gender (sex) impacts muscle growth.

1. Current body composition
2. Age and hormones
3. Sex
