I’m getting short on time to workout, I normally get to the gym during my lunch break. I’ve decided to change my routine and I want to add core/ab workouts 15 min at the end of my general workout M/W/F, so I need suggestions for good core/ab exercises that I can utilize to hit that muscle group in a short amount of time. I’ve tried 15-20 ab workouts before, I’ve never been able to stick to them. I’ve found I enjoy workouts that allow me to progress and increase weight, so I’d really like your suggestions on dynamic movements where I can progressively add more weight and overload the muscles for the best results. Seeing everyone progress has really motivated me and I want to really make some positive changes. Thank you!
