Fitness fads may come and go, but there’s one aspect of strength training we can all agree on: a strong core never goes out of style - and for this, I'd recommend the side plank exercise every time.
To some, it may look like an easy alternative to the classic plank, but those who've tried it will know that the side plank's simplicity belies its efficacy. Unlike many core exercises, this one engages and activates the entire body, not just the 'superficial' ab muscles. So, as you might expect, it's a little harder than the regular plank.
