This guide will provide you with several sports and fitness build hacks. You can have real fun creating these builds in your Minecraft world.
Basketball Hoop
The first one is a classic, but there are many versions. This is a clean-looking basketball hoop with a detailed and compact design.

Pool Table

Here is a pool table with pool cues. You can play pool on it anytime.
Gym

This is a pretty cool design that works well in a gym. It is somewhat complex to build, but worth the effort. You can use layers of snow to position the armor stands. Make sure the armor stands are facing straight ahead, which may take some time to align properly.

You need to carefully line up the “necks” of the armor stands.

These caps will form the conveyor belt.

You will need one final armor stand in the middle. You can use a cobblestone wall to help line it up. You may also add a small display at the front, such as controls for choosing the pace. After that, you can complete the rest of the gym.
Ping Pong Table

This is a compact ping-pong table, where a snowball acts as the ping-pong ball. For a more functional design, slime blocks can make you bounce even through the carpet. It is fun to play around with.
Barbell Weight

Here are some simple barbell weight designs to help your gym builds look complete.
Bowling Alley

Lecterns work well as gutters or channels, while end rods resemble bowling pins. Add a few lanes and you will have a complete bowling alley.
Punching Bag

This is a quick and simple build. You can use chains to create a punching bag.
Climbing Wall

This is a niche design that starts with an interesting wall layout. Add different difficulty climbing paths to complete the build. This example shows a very compact version.
Dartboard Cabinet

This design pushes the limits of how much detail can fit into a small space. It features an open dartboard cabinet with doors holding darts. It takes some imagination, but it looks great in a bar setting.
