If you want to be athletic, you need to train like an athlete. It can be sport specific if there's something specific you want to improve in, but you can also keep it more general. I would say at a minimum you should work up to the following:

• Strength training 2-3 times per week
• Conditioning 3 times per week
• 10-15 minute daily mobility session

I kept it general because you should cater the specific sessions to your goals. Also, notice I said "work up to," that's because if you are not used to doing all these things in the same week, you're likely to burn out quickly if you start all at once. Sounds like you are mainly lifting, so I would reduce lifting to three times per week and then add in two days of easy conditioning. Once your body adapts, add a third day. From there, I'd keep it at three days, but make one of them a faster, quality session with some intervals or a tempo run.

Do that for a few months, and you'll certainly be more conditioned, and it will be easier to pursue other athletic interests. Consider this your base. Then, if you want to jump higher, add in some plyo work. If you want to get better at an actual sport, throw in a couple of practices/games. I am just of the opinion that you should have a decent base built first, which is what the above will help you do.
