At first glance, the isometric exercises may not seem to have much use in building rippling stomach muscles, but when looking at the science of training principles you will come to understand the great role that isometric exercises can contribute to your abdominal development.
Isometric exercises are a type of training exercise in which your joint angle and muscle length remain static. There is no movement of your muscle or joint as resistance is provided by either an immovable force (pressing against the ground or a wall) or holding a static position (imagine holding a bench press bar half-way between its range of movement ). Rather than pushing the bar through a range of motion – up and down (dynamic movement) you remain static. This type of training only increases strength at the specific joint angles of the exercise, which is where isometric exercises seemingly fall short.
- Lie down sideways and support yourself with one arm. The other arm rests on the hip or even can lifted straightly.
- It's very important that you keep your entire body straight. The legs have to be extended and in one line with the spine and the head. Don't let your hips hang!
- The forearm of the supporting arm is flat on the ground and the hand is closed. You can also do this with the hand opened, but I I recommend you close your hand and contract your forearm slightly.
- The angle between trunk and supporting upper arm is 90°.
- To challenge yourself and take it to the next level, you can lift your right arm straight up towards the ceiling while doing this exercise.
- Hold this position for a count of 10 to 30.
- Repeat for 3 to 6 reps and repeat on the other side, if it is 30 count or 2 to 3 rep if it is 60 count.
