The goals of the first phase of training are to prepare the body for the future demands.
The objectives of Phase 1 are:
-
Balance
-
In this phase the body acquires balance and good posture. The core muscles will be developed in this phase. The abdominal and back muscles are the key to maintaining a good posture and balance.
-
-
Prevent injuries
-
The exercises are designed to condition the muscles, tendons, ligaments and joints to support future demands.
-
-
Overall Fitness
-
By adding cardiovascular activity, the body is able to transport essential nutrients to the muscles more efficiently. This prevents pain and fatigue during exercise.
-
-
Coordination
-
Coordination depends on the nervous system. These exercises train the nervous system to synchronize.
-
-
Determine the correct way to perform the movements
-
Each exercise has a posture, coordination and specific movement, with Phase 1, the body learns to automate and improve movements.
-
The above objectives will be achieved using low intensity exercises with multiple repetitions emphasizing balance and body posture.
Each week the difficulty of the exercises should increase to challenge your balance.
Phase 1: Balance & Core
Phase 1: Balance Core Exercises
1. First, choose exercises from the Warm-up page and write them in your Daily Exercise Plan.
2. Second, in your Daily Exercise Plan, choose 3 of any of the following Balance exercises and write them in your Daily Exercise Plan.
3. Visit the Stability Exercises with Resistance and continue filling your Daily Exercise Plan.
Note: We recommend that you initially perform the exercises in front of a mirror to make sure you have a good posture.
Each exercise has variations, if an exercise is difficult for you; start with a more comfortable variation. Also, if the exercise becomes easy use another variation to increase the difficulty. Do not change the difficulty before a week has passed and only if you feel comfortable with the new position.
