I love using the gliding discs in my boot-camp classes but my clients and students don't love them, because the discs literally kick their butt. So, I had to develop a gliding disc boot-camp workout for all my frugal exercisers. If you don't have gliding discs, use a hand towel for tile or wood floors and for carpet, use something plastic like a frisbee.
Gliding Discs Lunges
Keep your knee over your ankle when lunging.
Keep your wrist over your shoulders and keep your abs tight.
Keep the bent leg as still as possible as you bring the engaged leg back and forth
as quickly as you can.
In and out planks
Bring your legs in and out and keep your abs tight.
Level one: Lift up your glutes, slide the legs out, slide the legs back in and then lower
your derriere back to the ground.
Level two: The same as level one but keep your derriere elevated don't lower it at
the end of the movement.
Level 3: Do level one but cross your arms over your chest
Level 4: Do level two but cross your arms over your chest
