As Coaches and players, its sometimes good to remind ourselves of the basics of training
Specificity - To Improve a given skill,movement, etc , its best to practice what you want to improve
Individualisation - Different players respond differently to different types of training.
Overload - For change and gains to happen, the body/team must be pushed beyond what it currently does. Here are different ways it can be done
Frequency - Train more. Given adequate recovery, the more we train with the right type of training, the better.
Intensity - How much work can you get done in a set period of time. More the better.
Type - Change up the type of training - BodyWeight V Free Weights
Time - How long each session actually sends
Adaptation - Once pushed beyond its normal limits, the body learns to adapt and accept these limits as normal
Reversibility - Once a player stops training, the gains made will gradually go in reverse until the player is back to where they started or worse. Complete rest of more than 2 weeks is not recommended.
