A strong core will help you generate more power while playing your favorite sports, plus you’ll look good and feel great on the beach this summer.

Core exercises can be boring, but they are a necessary part of every successful fitness routine. Luckily, the DailyBurn trainers can help you keep it fresh with these core exercises.

Side Plank – Get into plank position and lock one arm as you balance on it and turn to the opposite side. Hold for 30 seconds. This exercise works your obliques. Repeat for the opposite side.

Weighted Side Twist – Stand with your feet a little wider than hip width apart. Hold a weighted medicine ball and twist back and forth as fast as you can, using your abs to accelerate and decelerate the ball.

Weighted Hundred – Lie on your back and lift your legs up with your shins parallell to the ceiling. Hold two small weights in your hands, and lift your shoulders while contracting your abs. Hold and pulse your arms (keeping them straight) for 100 pulses. Release. This exercise will definitely make your abs sore for a few days.

Russian Twists – Get in sit-up position and crunch your abs while lifting your shoulders. Hold, then twist from side to side for 30 reps.

Kettlebell Sit-up – Lie on your back and and plant your feet on the ground. Hold a kettlebell over your head. As you squeeze your abs, lift your shoulders off the ground and complete a sit-up with bringing your arms forward while holding the kettlebell with both hands.

Try completing this workout a few times a week to strengthen your core. Try cutting out processed foods and adding more fresh vegetables to your diet to increase your chances of seeing ab definition faster.
