"4 Essential Kettlebell Exercises for a Stronger Core"

Ab isolation exercises can help strengthen the core and potentially develop a six-pack, but it's important to understand the best exercises and strategies for training. The rectus abdominis (RA) is the main muscle targeted, and core training involves more than just ab exercises. Situps and planks are popular but not the most effective, with deadbugs and ab rollouts recommended instead. Gender doesn't determine the best ab exercises, and training frequency should be based on individual strength levels. Visible abs depend on both muscle size and body fat percentage, and spot reduction of fat is not possible through specific exercises.
