2 Of the “World’s Hardest Planks” [Tutorial]

Forget crunches and sit ups.  I've been barking about the dangers of too many sit ups and crunches for years.  As someone who has congenital spinal stenosis, I am hyper aware of what movements cause potential back pain and make your discs bulge.  If you've never had back pain, either an acute onset (a sudden accident) or chronic pain that comes and goes, it's hard to give up all doing crunches and sit ups.  But you still should back off of them if you do more than a few dozen a day.  That repeated motion wears away the outer lining of your intervertebral discs over time.  Discs are one of the few body parts that don't have the means to regenerate themselves after they're damaged.  And, if you do suffer from back pain, you should definitely give up the sit ups and crunches as a general rule.  Planks are your go-to solution.  And the harder they are (like the "World's Hardest Planks" below), the faster they work to flatten your abs and strengthen your core! That said, I do teach group classes, and I will throw my students a bone with some V-sits, small tiny resistance crunches with a Pilates ring and a few roll ups because the stretch feel good. I keep those types of exercises to a minimum now and don't recommend doing them daily.  That's why I'm a plank lovin' fool!  I do dozens of different variations.  Here are 2 of the "World's Hardest."  I heard a trainer who I highly respect refer to the first of the 2 exercises by that name, so I kept...

Bikini Season? Set Your Abs On Fire! A Squishy Ball Workout for a Flat Tummy

They're inexpensive and all you need to spice up your current ab routine.  You don't even need a fitness brand model (although plenty exist from maker like Bender Ball, Spri, and others).  Get a small squishy ball, about the size of a cantaloupe and watch this video to see how fast you can blast your abs into submission.  Form is key of course, so listen to my cues and keep those ab muscles "braced".   Safety tip:  unless the ball is between your shoulder blades, it's safest not to lay all the way back so you don't hyperextend your lumbar spine.  If you need a break, sit up.  If you need a little extra balance support, spread your arms out to the side and place your hands on the floor.  Hands in the air or behind the head is harder. https://www.youtube.com/watch?v=S_XWQZkcYCs...
