If you're a runner or a hiker like me, you'll know the importance of having a strong core. It's also essential for everyday movements like twisting and bending down. Last year, a trainer told me they'd swapped the regular plank for the Copenhagen plank, and I did the same after hearing the benefits.
The Copenhagen plank appealed to me more than other core exercises and side plank variations I've tried in the past. I could support myself throughout the movement, so I avoided wobbling while still challenging my balance and stability. In a regular side plank, where you rest on your feet, I find there's not enough support. I spend more time readjusting to avoid pushing my ankles into the floor than actually doing the exercise.
