If these ABS routines are your only workouts during the day, you should rest at least 2 to 5 minutes between the two workouts. If you are doing other workouts, perform the first abs workout at the beginning of your training and the second abs workout at the end of your training.

Yes, this challenge is very short and focuses only on your abs and obliques. If you are used to training longer, just add these 6 minutes abs to your regular training routine.

I know they are pretty challenging and you should definitely try doing them properly, meaning focus on the form and don’t compensate the movement by arching your back or losing body alignment.

If it’s too difficult, do the easier version of the exercise, for example:

• in Leg Pull-in or V-Ups place your hands on the ground behind your back,
• in Side Plank Abs Exercises place your bottom knee on the ground or support your position by placing the hand on the ground,
• in Raised Legs Circles or Criss Cross Up-Down you can bend the knees,
• in Reverse Crunches grab something stable above your head,
• in Side Crunches place your bottom straight arm on the ground and help to lift yourself up by pushing also from the arm.

I wouldn’t recommend to do ABS exercises during the period time.
