First of all, anyone seeking this type of rigorous activity -- especially near 40 years old -- should be in excellent condition and very flexible.
People often email me asking about swimming skills and techniques to get better in the water. Here are many tips that you can use to improve your swim times and confidence in the water.
Buy some swim trunks: Some of the simplest ways to get better in the water is by wearing proper swim gear. Recently, I was coaching some college students in the combat swimmer stroke and kept advising them to buy a pair of swim trunks and stop wearing the long baggy board shorts to try to learn how to swim. I tested them one day in baggy shorts and they swam in the 10:30-11 minute zone for the 500 yd swim. With no extra instruction, two days later, I tested them again in the 500 yd swim and they both had biker style swim shorts on. The difference in one was a 9:45 ￂﾖ formerly a 10:30 and the other dropped from 10:50 to 9:30. So just by wearing a real pair of swim trunks they dropped 45-80 seconds off their 500 yd CSS swims. I know to swimmers, this information is elementary but you would be surprised at how many people do not realize this:
Prepare with fins - 99% of your swims in any spec ops related course will be with fins. At BUD/S, you will swim all your timed ocean swims in fins even though to get INTO BUD/S you have to swim without fins. Learn how to do both on your pre-BUD/S fitness journey. I recommend SCUBA fins with dive booties. They will issue you UDT Duck Feet or US Diver Rocket Fins at BUD/S so if you are looking for a pair of fins, buy those. If you have a sturdy pair of SCUBA fins, those are fine. Wearing a thin pair of slip on flippers will not cut it though. You need something you prepare your ankles for the long ocean swims and dives done in sturdy SCUBA fins. Here is a common email:
Recently I bought a pair of Rocket fins and booties. Up until now I have been using soft fins for your workouts and I have been able to fin 1 mile under 30 minutes with soft fins. With rocket fins, however, it feels much more awkward and painful. It seems as if my arm-pulls get me more propulsion than the flutter kicks with rocket fins.
1. Is there a specific technique to swimming with rocket fins? Does the kick have to be a certain width? It seems that bigger kicks give me a stop/start movement and interrupt my momentum but while smaller kicks give me constant movement they still don't seem to propel me that fast.
There is a technique to swimming with fins, but no one best way as we all have different kick strengths. I have found that athletes in sports like football and soccer may not be the best swimmers without fins, but when they place a pair of SCUBA fins on their legs, they are faster than most people in the class. This is because they have well developed leg and hip strength and can use bigger kicks to build speed. Some athletes with less strong legs / hips tend to still swim fast, but are required to kick using smaller strides at a faster pace. You have to find out what works best for you personally. You will want to learn how to swim on both sides as well because you can alter your kick as long as your top leg always extends forward on both the left and right side. Learning to swim on both sides offers a form of ￂﾓrestￂﾔ by changing the pull ￂﾖ push stride of your left / right leg.
As far as arm pulls and breathing as pictured in the video, the arm pull can be used as another method of propulsion, especially if you need to rest your legs by skipping a few kicks throughout a long distance swim. Many people like to do a slight pause of kicking when breathing and recovering the arms forward again to remain streamlined. As with any swimming, recovering your arms should remain stream-lined and not an obstacle to forward motion.
2. The fins seem to cause pain in my feet after a couple hundred yards and stiffness up the front and side muscles of my shins. Is this just a matter of conditioning and getting my feet used to wearing these fins?
It is a matter of conditioning. When first wearing fins while swimming, you should only swim a few hundreds yards and push slightly past discomfort in the ankle and shin area. Do not push too hard and for too long at first as over use injuries like tendonitis in the feet and knees can flare up causing you to only be able to swim or run with severe discomfort or injury. This process usually takes about 10-15 swims or two to three weeks of swimming with fins. It is recommended to swim 500m with fins and if they start to bother you, take off the fins and swim 500m without, then try fins one more time until discomfort returns. Do this for a few weeks and you will be able to add greater distances each time you swim.
Mask or Goggles? - In any Spec Ops training program you will wear a mask, so it is smart to start training with a mask versus a pair of goggles. However, prior to BUD/S, you are not allowed to swim the 500 yd swim (at boot camp) wearing goggles so get used to it without goggles as well. I like any soft nose mask made by Dacor or US Divers.
