While the main thrust of the time spent training is focused on reducing a player's 40 time and other drills while gaining strength and explosion, there are a number of additional services that can be provided. 

Some locations provide massages as a basic part of the package, while others provide them a la carte. Rehabilitation services are also a critical part of the package for some facilities, and some keep physical therapists and/or orthopedists on staff full-time to attend to injured players. Another common add-on is interview training provided by ex-NFL scouts or administrators; there's even one former NFL GM who provides such training full-time at a rather expensive rate. His specialty is covering the questions teams commonly ask at the combine and on team visits, especially for players slated to go in the first three rounds and/or those who have background issues that may create trouble. Interview training has become so common that some see it as a necessary part of the process; different facilities provide their own spin on this practice, bringing in a local team official, using a sports psychologist, or perhaps even an ex-actor aimed at training athletes to be calm in front of the lights and cameras.

 

Who gets training?: More and more, players eligible for the coming draft see combine prep as a right or an entitlement, and expect their agents to provide it. As a rule of thumb, all non-kickers invited to the combine (around 350 players)  will probably train somewhere other than their school (though some will opt to stick around). After that, it kind of varies. Some players will find agents with open checkbooks who see training as part of the process, and these agents might give their clients pretty free rein about deciding where they'll train. Such agents are becoming more and more rare, however, as combine prep costs rise and some question its benefits over training at school. 

Recently certified agents are most likely to be the ones that offer to cover combine prep for virtually anyone they sign as an incentive in the face of their inexperience and limited (or non-existent) client list. This has become a classic mistake, as many athletes pursue an agent who offers all-expenses-paid training over one who may offer a less-enticing training package, but who is willing to work hard, be responsive, maintain a good communication level, and overall do the things a good agent does.
