All law enforcement training must make sense in terms of when officers are asked to perform different exercises and types of exercises. An example of sensible programming is scheduling heavy load days separately from speed days. In addition, scheduling speed days at the beginning of the week while recruits are not depleted of their energy is an example of sensible programming.
Trainers should understand the concept of energy depletion and that high-energy workouts should be situated separately and at the beginning of the week from other less depleting workouts. Lastly, plan to train different muscle groups on different days. Muscle groups should not be subjected to continuous load without time for proper recovery.
The final take-away is that trainers have to maintain realistic expectations and understand that injuries and setbacks occur during a training program from time to time. The key is in the reduction of such injuries. Take a look at the participants in your program and notice the varying degrees of physical fitness and body morphologies. Maintain an appropriate standard, but remain flexible in the way that you attain benchmarks. Require consistent effort and substantial progress, but remember there is individuality in each officer's physical journey.
Your ability to provide the personal attention many of participants need is very limited and may require more time than allowed in a class environment. If possible, offer your time before or after scheduled training sessions for corrective exercise demonstration to assist officers.
Understand that training in a group or team setting can be a challenge. Take heed of the famous concept of K.I.S.S. (Keep It Simple, Stupid). I have no idea who thought of this beautiful phrase but I've found that following it makes training much easier and successful. Sound and realistic planning in the beginning, along with recognizing your limitations with the group, will keep you progressing in the right direction.
