No need for preparation. Get down and do it.
Begin on your knees if that's all you can manage.
Get down on your elbows and forearms, and hold your body core straight while balancing on your toes.
And keep that butt down.
Do it for 10, 20, 30, 60 or how many seconds you can handle.
Do it by breath count. A slow four count is about 30 seconds.
An eight count is about a minute.
Modify a workout by doing splits. 30 second plank, and a minute rest, and repeat. Or try a 30 second plank and a 45 second rest. Maybe you want to try a minute of each, or a minute plank and 30 second rest.
Work your way up to as long as you need.
Do it once a day, or as often as you like. Watching TV? When a commercial comes on, do a plank.
Drop down in the office for a minute during a coffee break.
You'll strengthen the core muscle of your body, and that's the best foundation for a healthy body.
It's one of the simplest and easiest exercises you'll ever do.
Teach this to someone and get them on the way to having a healthy body too.
