Another piece of equipment whose value lies in its versatility, a box step can be used almost any which way. Box jumps, step ups, and lateral leaps are popular step exercises, but you can also use it as part of your strength routine to add variation and difficulty to exercises like push-ups, hip abductions, lunges, and squats.

Don't dismiss the importance of post-workout recovery. Self myofacial release, or self-massage involves the process of using a foam roller or plastic massage stick to release muscle tension and stretch, unknot, and realign muscle fibers. Storing a roller at home will ensure you can regularly incorporate SMR into your workout routine, helping you complete all the necessary steps to achieve optimal performance.

Add a new element to your at-home exercise routine by including Pilates inspired "glider" moves to your strength regimen. Try lunges, push-up pikes, or single-leg side squats. There are a million ways you can use these two simple discs and all are sure to make your muscles feel the burn.

Forget fancy cardio equipment like treadmills, bikes, and the elliptical. A jump rope workout will get your heart racing just the same, if not faster for a fraction of the cost.

Kettlebells are great at-home workout tools because they offer all the benefits of weightlifting, but go above and beyond what you can do with a typical dumbbell. Exercises like kettlebell swings, cleans, and snatches add an extra calorie burn by incorporating a cardio element to your strength training routine.

Maybe this item seems overly obvious, but don't disregard the significance of clearly defining your workout space. It can help keep you focused and motivated. Plus padding for elbows during planks and protection for your palms during push-ups might mean the difference between finishing your set and giving in to discomfort.

If you're not into shelling out for an in-house personal trainer, try inviting a virtual fitness personality into your home via YouTube instead. The best part about most of these workouts is that they offer a great burn but require little to no-equipment.
