Purpose: If you are forced to practice inside a gym you do have options. Of course, the players will wear the proper footwear and the safety of player/facility will be protected as well.

Procedure: Set up practice indoors with the equipment needed. In this case, the team is working on hitting. So the team can set up sock nets, buckets of baseballs, bats, and tees. The players can work on tee drills and soft toss drills.

Using the lines on the gym floor, the hitters can work on bunting.

Coaching Point: When forced inside, there is no reason not to practice. Lead your team and find a way to get work done in a gym. These are just two ideas. I am sure you can think of more.
