I'm a personal trainer — use these 3 bodyweight ab exercises to build your core and strengthen your upper body

The next time your core workout needs a glow-up, try these three bodyweight abs exercises and a short 15-minute routine. I use them regularly when I want to put my midsection through the wringer. 

I recommend one of the best yoga mats to support your lower back, but you won’t need any other equipment like dumbbells, resistance bands, or kettlebells unless you choose to add them.
