I do a variation of HIIT in the lap pool on non-lifting days. My current regimen is as follows:
>8 lengths at about 50% intensity to warm up
<Interval 1 - repeat 4 times
>1 length at 100%
>1 length at 60%
<Interval 2 - repeat 3 times
>2 lengths at 100%
>1 length at 60%
<Interval 3 - repeat 2 times
>4 lengths at 100%
>2 lengths at 60%
>Walk the length of the pool until you've recovered
>Do it again
I look silly doing this next to people doing endurance training but idgaf. I have adjusted this plan to correspond to my fitness level. You might need to do more or less. That said, when properly adjusted to your fitness level, I don't think there's a better way to do HIIT training (or any cardio exercise for that manner) than in the lap pool. High-intensity swimming is so much better than doing intense polymetric / CrossFit dumbfuckery and injuring yourself.
