What statistical analysis should I do?

Hello, I have one group of 23 participants, they performed 2 exercise protocols and measures was assessed two times. After checking normality, a two way repeated measures ANOVA was performed but I want to divide the group of participants in 2 sub-groups (males versus females) to see if when i add a between subject factor (gender) I will have other outcomes or not. What statistical analysis I have to do? I'll really appreciate your help.
