Specialists believe it’s better to organize the exercises into 2 workout plans and switch between them at certain intervals:

• Workout plan 1: plank (1 min); push-ups (1 min); squats (2 min); bird-dog (1 min); hip bridge (1 min); plank (1 min); push-ups (1 min); squats (2 min).
• Workout plan 2: plank (3 min); bird-dog (3 min); hip bridge (3 min); push-ups (1 min).

On the first week, start with workout plan 1 on the first day, then switch to plan 2 on the second day and so on, taking a rest on day 7. On the second week, start with workout plan 2 on the first day and switch between the plans in the same way you did during first week, taking a rest on day 7. Come back to the week 1 schedule after week 2.
