Weight & Training
by bobbby2dreki
Weight & Training is a Fabric and NeoForge datapack-based mod that gives every item in the game a weight, with strength training and exhaustion systems that players build over time.
What it does
The mod adds a weight to equipment, including weapons, armor and tools, through a datapack that works with the max weight attribute. Carried weight is compared against a strength value, and a default of 10 applies until a server owner changes it. Heavier loadouts, such as a full iron set with an iron sword, bring debuffs, while higher tiers like diamond and netherite scale more slowly and cause milder penalties. Changing the default strength value requires a reset of existing strength values.
Strength rises through training, and a longer training time raises it further, so the example setting of 20 doubles the time needed to gain one point of strength. The system also adds an exhaustion mechanic: harder training and staying awake longer build up exhaustion, which sleep reduces. Strength can be customized per server as a global setting or per player as a personal one, and a value of 0 disables the system. Weight & Training requires Fabric API and uses Mod Menu and YetAnotherConfigLib (YACL) as optional dependencies for configuration screens.
Key features
Weight on equipment
Weapons, armor and tools all carry a weight, so heavier gear affects the player as strength falls short.
Strength training
Strength increases with training time, and the training duration can be set to slow or speed progress.
Exhaustion build-up
Harder training and longer periods awake raise exhaustion, which sleep clears.
Global or personal strength
Strength can be set once for a whole server or adjusted for each player, and 0 disables it.

What the author says
Right now the default is 10. So if you put this to 20, for exemple, the training time will double. Then I would recomand the following value for the default strength: 26
