Tyler Martinez no worries. The main caused of muscle fatigue are dehydration, vitamin D deficiency (which being in the sun is likely NOT the issue) and build up of lactate in your muscles.

Hydration, eating fruits, and deep breathing will help to rid that lactic acid buildup.

If you plan on resting for a while and notice specific areas of soreness (calfs, shoulders etc) you can also foam roll (would look somewhat silly on the beach) but you can carry a golf balls or a few tennis balls taped together to help roll out some sore spots. I always have a golf ball with my cause my one Calf always cramps up while surfing.

Forgot to mention that you can also go to a vitamin supply store (GNC, vitamin shoppe, etc) and get some BCAA to add to water. Lots of weight lifters, gym rats, swear by it from interworkout recovery.

Hydrate! Water maybe add some liquid IV or even a tiny amount of salt. Salt helps with absorption (so I've been told).

Small snack: protein bars, trail mix, fresh fruit (something along those lines).Nothing too heavy especially if your plan is to surf again in a little.

Recovery breathing: Wim Hof breathing (plenty of youtube tutorials you can check out.)

If possible try to get out of sun for a little as that can be very draining.

As far as while being out back to recover I think breathing is gonna be your best bet there. Slow controlled breathing from the diaphragm (any marathon running will probably tell you this type of breathing is key to last the race.)

I do have a rowing machine. I don't use it as often as I used to though.

Sam HILL they are very nice. They just screw into your fin box. Hang them in your closet out of the way, or mine are hanging in my garage which has 9' ceilings so everything BUT my 9'3" Log hangs up there. Wetsuits, leashes, boards. Easiest way I've found to store them and save space.

Also wanted to mention try different brands as well if you have a place to try them on. An O'neill MT fits me perfect but a ripcurl MT is too tight, and some companies don't have MT, so depending on your size one brand may fit better than another.

I have the O'neill hyperfreak zipperless and love it. I like it so much I plan on also getting the 4/3 version for mid winter. Lucky here in South Carolina a 4/3 is the heaviest I need to wear. I also own chest zip and back zip ones, from my previous life in NJ. I prefer chest zip or zipperless. I don't like the back zip cord thing, but it's honestly preference. They are all easy to get into, although because of the opening size the back zip would be the easiest.

I believe the general idea is the zipperless would be the "warmest" since the idea of it is to allow less flushing but having used all 3 types I would honestly say it's just a preference thing.

Go to a shop and try them on see which you enjoy the most

This is how I store my boards. Couple of these. Quick trip to home depot, buy some 1/2 inch pipe in a length you need, couple of 1/2 flanges, 2 elbow joints, and 2 4" 1/2 pipe sections, mount it into a joist in your ceiling and done. I also took some pool noodles, cut them into small section and put them between the hangers to stop the boards from banging together. Keeps them off the floor and out of reach of my kids.

Yeap. Paddle out as close to the pier or jetty as you can usually. The water tends to rush back out to sea at these points and you can usually glide your way out there with very little paddling, just riding current and duck diving.
