Add this three-minute finisher to your workout if you want a stronger core

If you want to improve your core strength, you don’t have to spend hours doing sit-ups. You can challenge and strengthen the muscles in your midsection with this quick circuit below, and it only takes three minutes!

Add this six-move finisher to your workout, perhaps after this equipment-free upper-body workout, or beginner home workout.

Core strength is important for posture, balance, spinal stability and injury prevention. And if you suffer from lower back pain then working on getting a stronger core can help reduce symptoms. Plus, when your core is strong, it means you can move easier and perform better in sports and during exercise.
