I don't know about you, but I'm tired of working out in my living room I want the bright lights of the gym, the wall-to-wall mirrors, the endless dumbbells But once I get back to the gym, I'm a little lost Now that the equipment is well stocked, I went to YouTube in search of inspiration to find a new workout to try, and found Caroline Girvan and her 15-minute dumbbell abs workout video At the time of publication, it had over 13 million views I decided to give it a try

Of course, you don't have to do it in a gym All you really need are dumbbells (if you're looking for dumbbells to add to your home gym, I've handpicked the best adjustable dumbbells here) and an exercise mat (yes, I found the best yoga mat too) I chose 5kg dumbbells at my gym, but you want a weight that feels challenging enough to give you a good workout, but not too heavy to injure you

The workout itself is easy and Girvan does not give verbal instructions, so you can watch on mute and play your own podcast or playlist The workout consists of 15 different exercises, each lasting 50 seconds, with a 10-second break between each My core was on fire for several hours after I left the gym My core was on fire for several hours after I left the gym

One of my favorite things about YouTube workouts is engaging with my new instructor She is a perfectionist From her excellent form to matching her gym kit to her title card, her videos are expertly produced and fun to follow As mentioned, there are no verbal instructions during the workout I am now hooked on the real-life podcast and was able to keep listening to it while I was at the gym

I had hoped that the addition of dumbbells would enhance the ab workout, and it really did In a previous workout review, I had mentioned that I suffered from sciatica from a horseback riding accident when I was a teenager I soon realized that my ego was winning out and that some exercises required me to swap to lighter dumbbells to get my form right Heavier weights don't always mean faster progress

I often opt for workouts that get my heart rate up and burn more calories, but this workout definitely did not fall into that category With many of the exercises, the goal was to move slowly, keep control of the exercise, and use the core fully for 50 seconds It was a challenge, but by the end of the 15 minutes, there was a deep inner tremor that let me know that I had worked my core muscles deeply I would definitely do it again if my core would let me

If you're looking for an abdominal workout to add to your routine, I tried some of the most popular workouts on YouTube See what happened when I tried the Lily Sabri 7-Day Ab Challenge, the Brettman Rock Ab-Solute Workout, and the Pamela Reif 6-Pack Abs Workout
