It's easy to get caught in the trap of 'if I kick harder I will stay up' or 'if i kick faster I will go faster'.  Balanced and relaxed is the key to a smooth front crawl technique and a smooth and steady leg kick is vital to preventing that sinking feeling.

Exhausted after just one length?  This could be why...

It is very easy to put too much into the kick in an attempt to gain propulsion and movement.  Keep in mind that the majority of the propulsion for front crawl comes from the arms.  Therefore a slower and more balanced kick is sometimes more effective. 

Sometimes a leg kick that simply balances the arm action is best for maintaining a smooth balanced body position and stroke.  This of course depends on the overall distance of the swim. 

Common Front Crawl Kick Mistakes That Cost Energy

It is very common to kick from the knees with this swimming stroke in an attempt to generate some propulsion and movement.  This can also lead to a very stiff and robotic kicking action.  The kick must originate from the hip and be a smooth movement with relaxed knee and ankle joints.

The basic exercises detailed in my How To Swim Front Crawl book will ensure a balanced and smooth front crawl kick. 

Another common mistake is to make the kicking movements too large.  In other words the feet come out over the water surface causing excessive splash and again wasting valuable energy.

A good exercise to practice the leg kick is holding a float or a kick board and kicking along the length of the pool with face down.  This will allow the swimmer to focus purely on the leg kick, ensuring it is a relaxed and flowing up and down movement.

If you still feel like you are going nowhere or your energy is being wasted, try wearing fins on your feet.  Don't become reliant on them, but they will help your technique. After all, your feet should behave like fins as you kick.

Basic Technique Explained...

The leg kick should originate from the hip and both legs should kick with equal force.

The kick for front crawl works most efficiently as the legs kick in an up and down alternating action, with the propulsive phase coming from the down kick.  There should be a slight bend in the knee due to the water pressure, in order to produce the propulsion required on the down kick.

The downward kick begins at the hip and uses the thigh muscles to straighten the leg at the knee, ending with the foot extended to allow the surface area to bear upon the water.

As the leg moves upwards, the sole of the foot and the back of the leg press upwards and backwards against the water.  The upward kick slows and stops as the leg nears and minimally breaks the water surface.

Ankles are relaxed and toes pointed to give an in-toeing effect when kicking and leg kick depth should be within the overall depth of the body.
