Furniture Sliders Workouts!
If you are looking for a cheap alternative to strength training, furniture sliders are a piece of equipment to consider investing in! Buy them at Lowes or Menards for less than $10. You can use your sliders to add variety to you in home workouts, while really focusing on increasing core strength. The sliders can be used on hardwood floors, or carpet (carpet is much more challenging). They are really great for a quick, challening workout at home.
