@jeremyriesen: One kettlebell. Four exercises. One brutal core finisher. 3 rounds. Iron Trident – 8/side Russian Twist – 10/side Overhead Sit-Up – 10 reps Hollow Flutter – 30 seconds Rest as needed between exercises and focus on slow, controlled reps instead of rushing through them. Save this for your next workout, and send it to someone who thinks they need a gym full of equipment to build a strong core. #sixpackworkout #absworkouts #absworkout #coreworkouts #kettlebellworkout
