However, I’ve begun to suspect that my core might need more attention. For a start, I’ve been experiencing backache when sitting at my desk and strengthening your core is one of the best ways to counteract this.
I also do CrossFit which often involves a series of gymnastics-based exercises and my lack of core strength can hold me back during those sessions.

There are eight exercises to be done consecutively without rest. Rayner recommends resting for one minute after all the exercises have been performed, then repeating that sequence a total of three times. It took me about 15 minutes and my core was burning by the end of the workout.
I know good form is essential during core workouts and I paid close attention to this, especially as my muscles fatigued in the second and final rounds. I tucked my ribcage in and squeezed my glutes while performing the leg raise so my lower back remained pressed into the exercise mat.
I also made a point of keeping my hips in line with the rest of my body during the mountain climbers and plank, rather than letting them hike up which takes some of the tension away from my core muscles and diminishes the challenge.
I'm pretty confident with flexion exercises such as sit-ups and crunches, which mainly engage the rectus abdominis muscles. However, the leg raises and climbers proved far more difficult which suggests I lack strength in my obliques and deeper core muscles such as the transverse abdominis. I love any workout that helps me identify weak spots so it’s one I’ll come back to regularly as a quick way to activate my entire core and put my strength to the test.
