Critical Swim Speed (CSS) is an approximation of your lactate threshold speed and you can find it by doing a couple of swimming tests. It's not precisely the same as lactate threshold but it will be within a second or so per 100m, which is plenty accurate enough to guide your training. The CSS test involves two time trial swims - a 400m and a 200m. Before attempting these swims perform a thorough warm up and a small build set to get you used to swimming fast. We add a third test to get your complete swimming profile. Do the 400m time trial first, it's less likely to effect the 200m than the other way around. Recover completely between each time trial with some easy swimming. Perform both time trials from a push off from the wall, not a dive. Try and pace the trials as evenly as possible, don't start too fast and slow down. If you're not sure get someone to take your 100m splits - they can be very revealing. To calculate your CSS go to: http://tritrainingharderllpblog.blogspot.co.uk/2013/10/swim-testing-critical-swim-speed.html Session: --------------- Warm up: Optional 500m Steady swim (Every 5th length do as Medley) 200m Mixed stroke 200m Drills (Own Choice) 100m Build every 25m Optional second 100m Build every 25m --------------- Main Set: 400m Time Trial - record the time Recovery swim until ready to do it again (mixed stroke) 200m Time Trial - record the time Recovery swim until ready to go again (mixed stroke) 50m Time Trial, record time --------------- Cool Down: 250m Mixed stroke

The purpose of this session is to improve the ability to work at lactate threshold. This is supposed to be easy to begin with, but as it carries on, it gets harder. Really focus on hitting those times. Note the times are taken according to your CSS/100m time and explained as so: If your CSS/100m = 1:40, then: CSS/25m = 25s CSS/50m = 50s CSS/75m = 1:15. Use this to help calculate rest and recovery time. This session works best when using a Finis Temp Trainer Pro (available in our online store). You can set this on setting 1 to beep at CSS/25m intervals. Therefore every time you push off the wall you should be in time with the beep. If you are training in a 50m pool, then the same should also be true, but you can use the 25m beep as a reference when you make it half way. You should not be aiming to swim faster than the beep and then easing off, you should hit the beep each time through the whole set. If you need any assistance with any drills, then please visit our swimming drill playlist (http://www.youtube.com/playlist?list=PL6z5VWjBAAEjY-gdl4EktRwwMQiAD_M0O). For mixed strokes, do both breast stroke and back stroke to open up your chest and arm muscles in either the warm up or the cool down. Enjoy...! --------------- Warm Up: 300m F/C 300m Mixed stroke, alternating Back stroke and Breast stroke 2x200m (20seconds recovery) as 50m Fast and fluid, 100m cruising, 50m finishing fast. --------------- Main Set: 27x100m @CSS/100m (CSS/25m recovery) --------------- Cool Down: 300m Mixed Stroke Cool Down

The purpose of this set is to build aerobic endurance and promote good technique while swimming. Throughout this session aim to hold good technique and focus on the rhythm of the stroke, especially on the longer intervals. For any drills, you may need fins (available from our online store), and you may also need the Tempo Trainer Pro (available from our online store). If you are unsure of what drills to do, then have a look at our you tube playlist of all the different drills we recommend (https://www.youtube.com/watch?v=uqTuVNRW9vo&list=PL6z5VWjBAAEjY-gdl4EktRwwMQiAD_M0O). For mixed stroke, do both back and breast stroke to help open your muscles and use them in different way to front crawl. --------------- Warm Up: 300m F/C – Easy 100m Back Stroke 100m Breast Stroke 100m Kick with fins 200m Side kick, with fins 4x50m as 10 strokes hard, 10 strokes easy. --------------- Main Set: All as CSS/100m+5 seconds with a CSS/25m as recovery. - 27x100m --------------- Cool Down: 300m Mixed Stroke Upper body stretching

The purpose of this session is to improve technique. It is also a bit easier so allows you a respite from the usual type of conditioning sessions. Here we suggest some swimming drills to use to improve your stroke mechanics. Most of these should be performed with swimming fins (You can purchase some on our online store). If you need any assistance with any drills, then please visit our swimming drill playlist on You Tube (http://www.youtube.com/playlist?list=PL6z5VWjBAAEjY-gdl4EktRwwMQiAD_M0O). For mixed strokes, do both breaststroke and backstroke to open up your chest and arm muscles in either the warm up or the cool down.
It is really important to get the drills correct, so take your time to be deliberate about the drills. Enjoy these more technical sessions.
