from a men's fitness magazine, my husband gave me this work-out that uses your own body weight instead of free weight s or machine.
So , you start with chin-ups 2 sets 15

crunches 2x20 one crossed leg
crunches 2 x30 bent knee
crunches 2 x20 straight in the air legs

pushups 2x 15
dips 2 x 15
squats 2x30
lunges ( properly positioned with knee directly over toes)2x15
jumping jacks30
burpees2x15

It's hard excersise,,,,,,but you do get results Think about it,,you are lifting your own body weight

Initially this workout is OK.
But a problem with body weight workouts is you cant incorporate progressive overload. which is needed to ensure ongoing results
Also ,I beleive theres too much ab work involved. You are using your abs in all the other exercises and the abs are same as any other skeletal muscle in the body, So why train it differently?
Just my opinion.
