Hello Active Impressions.
To be perfectly frank with you, if the only thing you are willing to share with the Idea Fitness Connect community is that she has large breasts, I am not in a position to recommend any exercises. From my perspective, it’s like asking what exercises do you recommend for someone who has a big head.
I am sure you are aware that the development of an exercise program is based upon the collection of subjective and objective assessments and that there is no such thing as spot reduction.
You haven’t informed us as to whether you performed a postural screen, any fitness testing, the type of work that she does, whether she has any clinical conditions.
Way too ambiguous for me to offer a suggestion.
