Lying down on a cold, hard floor and putting strain on your neck and back puts a lot of people off training their core, and I don't blame them. Traditional floor-based ab exercises like sit-ups, dead bugs and crunches can feel really uncomfortable on the back, especially after multiple rounds of the same routine.
Thankfully, standing ab workouts exist, and even better, you can add one of the best kettlebells to really ramp things up. Trainer Shaina Faita is behind this five-move, all-standing kettlebell routine, and at the core (if you pardon the pun) of the workout is strengthening what we call the deep core muscles.
