Problem: How to work out chest muscles without weights
Perform basic pushups.
There are many variations of pushups that can help you build your chest muscles, but for beginners, there's nothing wrong with basic, ordinary pushups. That said, when starting push ups, avoid lowering your chest too close to the ground.

Answer: Lowering yourself too close to the floor can tear tissues in the shoulder. Gradually work your way to lowering yourself slightly closer to the floor over time.

Problem: How to refinish a coffee table
Set up your work area.
Because you will be sanding the coffee table and creating a lot of dust, it is best to work outdoors or in a garage. If this is not an option, choose a room that is well-ventilated and will not be needed for use during the refinishing project.
Answer: Lay down a plastic drop cloth to cover the floor of the room and collect the sanding dust. Make sure the room is not really in use by anyone else during this time period.
