The first thing is to decide what information you want to retrieve from the database. Do you want to pull from it those who have weight range for example.
Access is a relational database which allows you to relate to different tables. You seem to require only one table and Excel may well do what you want using the search and/or filter. If you haven't used Access before this may be the best approach as setting up Access can be time consuming although wizards do allow you to produce acceptable reports, etc.
Also consider the number of entries you need. If there is more than 1 entry per person then Access may well be the way ahead.
