The side plank is one of those exercises I find myself frequently tossing out of my quiver of training options, only to find myself continually coming back to it saying, "Why did I stop doing these again?" Or, "Tell me why I stopped giving these to my athletes?"
It's a fantastic exercise I feel should be included in the lion's share of beginner programs - to teach core stability, breathing patterns, resisting lateral flexion, etc. - but, it can also be extremely useful as a warm-up or "filler" exercise for more advanced trainees.
Bottom Line: You are never too novice nor too advanced for the side plank. It's just a matter of finding the right fit for you, personally. One of the defining beauties of the side plank is that it's so easily scalable for any individual or situation.
Here are 15 variations of the good ol' fashioned side plank, be you a beginner or an advanced trainee.
Oh, and don't be a fool like I was during these photos with the grody head positioning. Man, it's ugly. Apparently I didn't want to look the photographer in the eye as he snapped these.
The chin should be neutral, or "packed." Geeze, why did that guy in the red shirt demo these, anyway?
Level 1: Short Lever and Torso-Elevated
I personally find the knees bent, or "short lever," variation MUCH better suited for those who are new to training and/or are dealing with low back pain. And for whatever it's worth, I've found that, in some cases, elevating the torso may even make it harder than doing it on the flat ground.
If I'm working with someone on their first day, and I'm doubtful that they can do a normal side plank without collapsing in the first 5 seconds, I'll usually go with the short-lever first to set them up for success, and then progress accordingly if they feel good.
Level 2: Staggered-Feet and Standard
(Note: Staggering the feet is typically easier than stacking them)
Level 3a: Feet-Elevated Side Plank, Stable Surface or Suspension Straps
Level 3b: Weighted Side Plank w/Weight On Hips, or Weight Held Overhead)
You can certainly use a dumbbell, or even a weight plate, instead of a kettlebell on the hips, but for overhead holds I find the kettlebell to feel much more natural. The overhead chain hold adds a nice stability challenge, since it will want to sway on you.
Level 4: Side Plank + Band (or Cable) Row
This is one of those "fun" ones as it's less boring than remaining static, but it also provides all the benefits of horizontal pulling. I recommend performing it for 8-12 reps per side, with a 1-second hold at the top.
Level 5: Side Plank w/Wall Slide
This variation is downright miserable, which is why I had Tadashi demo it for me. To keep yourself honest, place a furniture slider under your heel. Start with the feet stacked, then slide your heel up the wall, trying your best not to make a pain face as your glutes light on fire.
Level 6: Weighted + Feet-Elevated
Level 7: Single-leg + Feet-Elevated with Top Leg Support, Single-Leg +Feet-Elevated with Bottom Leg Support
These are pretty advanced, and definitely shouldn't be just handed out to anyone and everyone. With the bottom-leg support, the abductors of that leg will become fried, assuming you are actually keeping your hips up, and when the top leg is supporting, the adductors of that leg will be screaming for mercy.
I generally like prescribe two to three sets of :10-:40 (depending) per side. If you can't hold a variation for at least :10 then it's probably too advanced, and anything longer than :40 per side is overkill for most. Or, you could combine all three variations into one set, holding each position for anywhere from 5 to 15 seconds.
