Week 12 - Rest Week
This week is intended to give you some rest from the intense training you have been doing.
You may swim 2 or 3 times, but keep intensity low and swim for less than 2 hours. This would be a great time to do a Form Practice, with low physical intensity and high quality attention, to look for features of the stroke you may improve.
You are encouraged to do other activities like walking and hiking as you please, as long as you do not exhaust your muscles or metabolic system.
You may do running, cycling, or other aerobic activities that last less then 90 minutes to not stress your metabolic system too much as it recovers from this training cycle. Please be very careful about activities or actions that might put strain on your spine or shoulder joints.
