The most important thing when structuring your workout is to have a game plan for the skill you want to improve. This should be determined before you step on the court. For example, do you want to be more consistent at pull-up jumpers, or work on increasing your 3pt range, or you want to get better at attacking the basket?
Now that you've determined what skills you want to improve, it's time to figure out which drills to incorporate. If you don't know which drills to do you can always search for drills in an app like HOOPr, social media, or YouTube. I'm a huge fan of breaking down drills and building back up. For example, if you want to increase your range, start with form shooting drills then gradually move back until you can shoot from the 3pt line.
You have a game plan, it's time to clock in to work! Start off with doing some exercises to get loose and get a good stretch. The first few drills should focus on fundamentals. Focus on repetitions to build muscle memory. As you progress through drills the intensity should pick up. By the time you get the last few drills you should be able move at game speed. One thing I like to do after I've finished my last drill is to go back to the first drill I started with and do it again. If I've had a good workout, the first drill will be easier and feel more natural.
It’s a good idea to create a chart and track the drills you did, the time you spent on each drill, and the number of reps you took. This helps you monitor your progress. It’s also a good time reflect on the drills that you excelled or struggled at. For the next workout you might want to focus on the drills that were more challenging and spend less time on the drills that were easy.
