Bouldering is good for building muscle, so I think your problem is you need to eat more. You can work out all day, but you’ll stay skinny if you don’t eat.

I’ve tried many things, one thing that worked for me being calisthenics - following the programs on r/bodyweightfitness on Spez’s Lemmy.

The reason it worked for me is because working from home, there were zero logistics, I could finish working (from my bedroom), and take my t-shirt and jeans off and start working out in literally 30 seconds. The programs also had enough variety in terms of different exercises to keep me entertained.

Now I work out with my partner (who is also on the spectrum, to make things more complicated). What has been working for us is doing some activities we like; on Mondays he has flamenco class so I go swimming, which I love - him going to his class is a good enough cue to kick my brain into “let’s do things” mode. Then we added Yoga on Wednesdays (the hard, “sweaty” type with lots of bodyweight type exercises to keep myself motivated). We both like it, and we take turns choosing a video to follow, so there’s incentive and novelty to do things. Once that’s fully embedded in a routine, we’ll add something else, let’s say gym on Thursdays. My strategy is to go for the maximum variety we can so I don’t get bored, and add things gradually so it becomes a de facto part of my routine and my brain doesn’t get to question the fact that Mondays are swimming pool day.

It’s been working well for a couple of months, and I suspect it will work well until there’s a major life change that derails all of this, but then I’m hoping I can re-plan the strategy.

Also to add about the specifics of swimming for ADHD: it might sound boring but no matter your level, if you push yourself hard you can leave yourself absolutely knackered in 40 minutes. I can get in a really good workout by the time boredom kicks in. Plus I count the laps I’m doing, I try to keep a mental count of what the percentage of my goal for the day that is… And that keeps my mind busy enough that I can’t think about other things that maybe would sound more exciting.

Do a strong lifts 5x5 program.

Focus on your body through the entire repetition and make the next one better.

The numbers going up on your lift value will be the game until your body starts showing you the score also.

I say this as a on the spectrum adhd man

Have you tried action sports like paintball or airsoft? They’re tons of fun, get the adrenaline and dopamine flowing, and provide both cardio and a solid core workout.

I’ve actually found weightlifting to be surprisingly satisfying. I really enjoy it because I get to compete against myself, and tracking the weights & reps gives me a very clear sense of progress. Weightlifting (and some low intensity cardio options) also allows me to do plenty of scrolling during my workout if I want to. The trick for me has been to find something that I can make a routine, and whenever I lose my routine, I work to build it incrementally. I’m actually really struggling right now because my gym made some changes that led me to cancel my membership, but having a physical location to go to seems to be a key factor for me.

Anyway, when I’ve needed to rebuild my routine in the past, step 1 was walking to the gym, but not going inside, and just walking back home. Since that entire process took about 30 minutes, it wasn’t too difficult to squeeze in if I overslept. Step 2 meant I had to actually enter the gym and do something. Usually it was just walking on a treadmill for up to 30 minutes, depending on how much time I had available. From there, I’d start adding some time in the weight room and increasing the intensity of my cardio time (running or stairs), and eventually I’d work myself up to an hour of weights plus 30 minutes of running.

Since I’ve cancelled my gym membership, I’m really struggling to stick to a routine. Going to a certain location at the same time every day seems to be important in keeping me focused. One thing I did find that I’m hoping will motivate me is a running meetup. They have routes of varying difficulties, and often grab a beer together after, so I’m currently trying to build enough stamina to feel confident participating in their easiest runs, and hoping I’ll eventually feel confident in their more challenging runs too. If running isn’t your thing, I’m sure there’s other groups for activities that you would enjoy.

I would like to introduce you to the game of chess on ice: curling.
The sport that everybody watches for a week during the winter Olympics, perhaps not realizing that it is extremely accessible and easy to get in to depending on where you live and your proximity to the nearest club.

Games are played with two teams of 4, with each player delivering 2 rocks per end (inning/frame) for a total of 16 rocks. While one player is delivering, the next two players on the same team act as sweepers and will judge the speed of the rock as it moves and relay that information to the skip; the team captain and fourth member of the team. The skip’s job is to call the shots as well as watch the rock as it moves down the sheet and emphatically tell the sweepers if they need to sweep or not. The two skips also get to throw the final 4 rocks of the end which are often key to determine scoring. The last rock thrown is called the “hammer” and is a major advantage. The hammer is given to the team that did not score the previous end.

Scoring is determined by how many rocks your team has closest to the center of the “house” (the coloured rings) which is the scoring area. Each rock is worth one point no matter where in the house it sits, as long as there are no rocks from the opposing team that are closer to the center.

As a “front-end” player, ie. the first or second thrower, your job will be to set up the beginning of the end by placing early rocks in front of the house called “guards” that are used to protect rocks thrown later on used for scoring. Front end players need to be very athletic and have careful control over their heart rate. Sweeping a rock effectively is a lot more strenuous than it looks and requires balance, strength, dexterity and focus. You need to be able to judge how fast the rock moving and where it might come to a stop while simultaneously putting your entire body weight onto the head of your broom while also moving down a sheet of ice at a jogging pace without falling down. You need to be able to switch from this burst of effort into being calm and collected in order to take your turn when delivering your next rock. Front end players will need to sweep 6 rocks every end.

“Back-end” players are the third and fourth players on the team. While the third does still need to sweep 4 rocks every end, the skip does not do any sweeping unless necessary, usually in the house. These players are generally the more tactical and precise of the team, able to figure out a strategy that allows either a score of multiple points, or even to try and steal points from the opponent when they have the hammer.

Curling is generally considered to be a social sport. Competition at the club level is not taken too seriously and most people are there just to have a good time. Depending on your local customs, you can expect to join your opponents after the game for a round of drinks.

I find it to be fairly ADHD friendly, when it’s my turn to throw as a front-end player I’m keyed in and focused for 60 seconds or so and then I can sort of zone out while it’s my opponent’s turn, and then when it’s my turn to sweep I find it a great way to burn off those calories. My heart rate easily reaches 120-130 a few times per game.
I would not however want to skip a team. Having to keep my mind in the game the entire time while watching every single person making shots and trying to figure out the correct next move is mentally exhausting and better left to others. Unless maybe that’s your thing, but games usually go on for 90-120 minutes.

I’m biased because I love it, but disc golf is a great sport to chill and play with buddies (assuming you can get them into it too). It has a low cost for entry - a few beginner discs won’t cost much, and lots of courses are either free to play or cheap for a round. It won’t make you a muscleman or anything, but it can build some arm, shoulder, and core strength if you play enough.

Aerobic exercise will pretty much never make you less skinny. So any sport that involves a lot of running is never gonna help you bulk up

Jiu-jitsu has been pretty good for me. I get into a really calm/flow state while practicing it.

It’s something I recommend everyone to try :)

It’s a little expensive to get started doing, but backpacking is awesome. My favorite time is when I’ve got dinner in the pot, my hammock is all set up, I’m hitting my THC pen, and relaxing. The views are usually really nice too if you’re in a nice area or are willing to drive a few hours from your home. Campsites/Park entrance is pretty cheap and your gear should last. If you do all your shopping online it should look like this.

Tent: ~$75 Shoes: ~$50-75 Backpack: ~$50-$75 Hammock (if you decide this over a tent): $40ish If you go hammock you want to get either a wool blanket and an underquilt which will be $50-$80 or you could just get a sleeping bag which will vary in price based on how awesome of a bag you need. You’re also going to want a bug net for the hammock. Get one that zips shut vertically. It can be a pain to get into the hammock with your phone, a meal, your blankets, and whatever else when you have no free hands and no head space. I think mine was like $15. I would also suggest one that has some sort of internal support frame. Mosquitos love me and I’m open tore up on one of my arms and one of my legs as they will bite me through the bug net and my hammock. They make sprays to keep them off your gear that last for long periods of time but I haven’t tested them. A water bladder: $20 You could get a filtration system, I carry like 5 liters of water. It gets really heavy. And a jet boil: $20-$30

There are other misc things I would suggest packing to. Medical supplies (band aids, ace bandage, some sting ointment, Advil/Tylenol, common stuff that should be around your house)

The rest is just food. Meals that don’t need to be refrigerated and if possible use some of your water. Soups are good if it gets cold at night. Take some vegetables and some bouillon cubes. Even some dry noodles and make a meat free chicken noodle soup. Or canned tuna and rice. I try to stay away from the dehydrated premade meals because there’s a ton of sodium in them, they are pretty expensive, and most don’t taste that great.

Most importantly, if you decide to pick up the hobby, please be safe when doing so. Start with short hikes, make sure that you have a compass that doesn’t need Internet to function (don’t rely on your phone) have print outs of your map, and let people know where you’re going. If you go to an official park, talk with the people at the front office before embarking. They will know of any deviations on the trail, good places to get fresh water that you can filter/boil if need be, any problem areas in the trail, and most interestingly, what trails have the best views and will fit your skill level of hiking.

I can send you links to what I’ve purchased as well as a short review of my gear as well.

Fencing.

Something about being 1v1 with an opponent and facing them in the closest sport to simulated combat other than a martial art just causes me to immediately hyperfocus during a bout. Probably the only time I’ve ever felt that ADHD is a strength.

Also in fencing being skinny is a super duper great advantage.

It’s fucking exhausting tho, a 2 minute bout will absolutely wipe u out at first, both muscularly and cardiovascularly.

You’ll be incentivized to lift and do sprints to improve your technique.

Practicing parries and ripostes is also anything but boring, with each repetition you really feel the intricacy of each motion and it’s never ever boring since you can just imagine your doing it against an opponent

You into tennis?

The only two sports that were lame for me because of the lack of stimulation were baseball and soccer. I liked basketball and hockey and tennis and racquetball. There were others I would have played had there been programs for, too. Like bowling and billiards (though these are questionable as “sports”).

This is just for playing of course. I can’t stand watching sports, even the ones I like playing. It just makes me antsy and wanna play! I’ve always kinda gravitated towards games, though. Sports are games, and my ADHD brain latches onto the game part and can ignore all the other parts that are boring or don’t interest me.

Can only offer you three points, 1 nope sports really are boring, 2 you mention planking, I’m no gym dweller but if you need more muscle, planking is the opposite of what you need to do, lift heavy things, short reps, high protien diet. 3 motorcycle racing, specfically silly stuff like moped enduro, the amount of fun and helpful people you’ll meet in the pits is crazy.

I for one, really love table tennis. Games are short, points are short, and there’s a lot of things to think about all the time.
