How to strengthen your abs, legs, and shoulders
Isometric exercise is a form of resistance training in which the participant uses the muscles of the body to exert force against an immovable object or hold the muscle in a fixed position for a set time. In this type of exercise, the muscle contracts but does not change length during the exertion of force. The joint most closely associated with the effort also remains static throughout the exercise.
Although isometric exercises can offer many benefits, there are precautions to note. People with high blood pressure should not engage in this type of activity because isometric exercises cause a spike in blood pressure. Although blood pressure typically returns to normal quickly once the muscle is relaxed, the spike can be dangerous for those who already have elevated blood pressure. If you have high blood pressure but really want to do isometric exercises, consult your doctor for tips on how to lower blood pressure first.
Other considerations when performing isometric exercises include how long each action is held and the angle of the joint when the action is performed. The duration of an isometric exercise is comparable to the number of repetitions in other types of strength training. For strength training, a duration of 3-5 seconds per exercise is optimal. However, when body weight is used as resistance, longer durations of more than 10 seconds are required. As for joint angle, it is important to note that the muscle will gain strength only at the joint angle at which the exercise is performed. People who want to gain strength through the entire full range of motion of the muscle should consider training at intervals of 10 to 30 degrees. However, this can be time-consuming.
The following are examples of different isometric exercises that help improve the strength of muscles such as the abdominals, shoulders, quadriceps, and calves.
The Plank - for abdominal improvement.
The plank engages many muscles; in addition to strengthening your abs, you will also condition your back. This is one of the best core exercises that exists.
- Start by lying flat on the floor.
- Slowly raise your body so you are resting on your toes and forearms.
- Keep your back flat and your abdominal muscles taut.
- Hold the position for 10-30 seconds.
- Repeat the exercise 2-3 times.
When this becomes easy, curl your toes under your feet to make it more difficult. You can also extend one arm forward for another difficult variation.

Isometric Shoulder Raises - for shoulder improvement.
- Stand with your feet shoulder-width apart and your knees slightly bent.
- Grasp a dumbbell in each hand and raise the weights out to your sides until they are at shoulder length and your arms are parallel to the ground.
- Hold the weights in this position for 10-30 seconds.
- Repeat the exercise 2-3 times.
If this is too difficult, try lifting with just one arm at a time, alternating, until you can handle both weights at once. If you do not have a dumbbell, you can also use bands or tubing in the same way.
Isometric Squats - for quadriceps improvement.
- Stand with your feet shoulder-width apart and your back firmly against a wall.
- Slowly slide down the wall until your thighs are parallel to the floor.
- If necessary, move your feet away from the wall to ensure your knees do not extend past your toes.
- Hold the position for 10-30 seconds.
- Repeat the exercise 2-3 times.

Isometric Calf Raises - for calf improvement.
- Stand next to a wall on one foot and touch the wall lightly for balance, if necessary, but do not allow yourself to rest against the wall.
- Rise up onto your toes.
- Hold the position for 10-30 seconds.
- Switch feet and repeat the exercise for the other calf.
- Repeat the exercise on both calves 2-3 times.
