Hangboard Training Program – José Antonio

José Antonio is a highly motivated climber from Mexico who likes both lead climbing and bouldering alike. When José Antonio and I met in June, he’d been climbing for over three years, and his personal best was 5.12a/7a+. After two months of following the program, he quickly sent his first two 5.12b/7b routes, and now he’s hungry for more! 

Since José Antonio was completely new to hangboard training, I decided to put him on a long and easy adaptation cycle to ensure that he doesn’t become overtrained or injured. The cycle was a mix of weighted hangs, Endurance Repeaters, Moonboarding, and lead climbing. Despite the seemingly low hangboarding volume, José Antonio improved his strength and aerobic endurance significantly, allowing him to enter the 5.12b/7b grade.

Here's what José Antonio says about the Program:

I was searching for a way to complement my training at home in 2020 because of the pandemic, and finding StrengthClimbing was not just what I was looking for but much more. I found a new way of training, which is addressed to the more specific requirements needed by a climber in order to get stronger and keep leveling up. I used to overtrain, but Jędrzej's personalized approach has given me also more time to dedicate to my daily life by training just what's most important. The result has been finding myself with more energy and strength when I rock climb, which makes me enjoy more Improving becomes an inevitable consequence!

Results of Cycle 1 (Strength/Endurance – Adaptation)

When José Antonio started the program, his MVC-7 on a 20 mm edge was 117%, and his Critical Force (CF) was only 28%, which is very low for a lead climber. After five months of an adaptation training cycle, his MVC-7 load increased by a remarkable 7 kg! In parallel, he managed to improve his CF to 35% MVC-7, which is a much more acceptable value. 

José Antonio is now ready for his training loads and volume to be carefully increased to ensure that he keeps progressing evenly without hitting a plateau.

Hangboard Training Program – Piotr

Piotr is an extremely motivated and experienced lead climber, who excels at crimpy slabs and vertical walls. He lives in Mexico, where he has access to vast areas of high-quality virgin rock, which allows him to bolt his own new lines.

To me, Piotr is a bit of a mystery because, based on the score from my lead climbing grade prediction algorithm, his level should only be 5.11d (7a). So far, the algorithm has been pretty accurate at estimating the current lead climbing level for other climbers on the program. And yet just a while ago, Piotr managed to send his fourth 5.13a (7c+) route. I believe that what Piotr lacks in terms of physical determinants, he makes up for with experience, technique, a strong mental game, and commitment. On top of that, being six feet tall gives him an extra edge on crimpy and slabby routes. 

Piotr is currently climbing a lot outdoors, so he follows a low volume hangboard training program, which strikes an equal balance between strength and endurance development. It also needs to be mentioned that Piotr never really trained on the hangboard before, so he still has a huge potential for physical development. I believe that if he combines his improved strength and endurance with his technique and experience, he will significantly progress as a climber.

Here's what Piotr says about the Program:

"Tired of reading, analysing, and piecing together everything I found on- and offline, I decided to look for help. Being a 43-year-old with very specific needs, I decided to contact various online coaches, who unfortunately could or did not want to take me under their wings. Through sheer luck, I came across StrenghtClimbing website, and upon having read all (sic!) its content in one go, I decided to contact Jedrzej to ask a few questions. He got back to me quickly, answered all my Qs and offered help with training. I started Jedrzej's training programme 7 months ago. At present, I can feel my fingers (crimping and grip) much stronger than before and my endurance has grown substantially. For the very first time, I am motivated to train on a fingerboard, which I had avoided and used infrequently before. I meticulously write down my results and J meticulously gets back to me with his feedback. In short, I have found my coach!"

Results of Cycle 1

When Piotr entered the program his MVC-7 on a 20 mm edge was only 114%, a result typical for a V5 climber. His critical force was 33% of his MVC-7, which is more common for boulderers than lead climbers. For sport climbers, this number normally lies above 40% and it’s not uncommon to see ratios as high as 50% or even 55%. Taking into account Piotr’s results, and the fact that he never trained systematically on the hangboard, I decided to put him on a balanced program, with a slight emphasis on endurance development.

Cycle 1 was three months long, from mid-June until mid-September when we ran the performance assessment. As a result, Piotr’s strength increased by 4 kgs, which is a very respectable 5% improvement. However, Piotr’s gains in terms of endurance were even more spectacular. In only three months his Critical Force went up to 40% MVC-7, and 47% body weight. In August Piotr confirmed his physical fitness by redpointing a 5.13a (7c+) project. 

I believe that Piotr still has some way to go before he’s ready to lead his first 5.13b route, but he’s on the right track, and with his commitment and discipline, it’s just a matter of time.

Results of Cycle 2

Cycle 2 was also three months long, from late September until the end of November. Regarding strength training, this time, we opted for a more relaxed approach, with shorter and less intense hangboard sessions and with a lot of lead climbing and a bit of gym bouldering. The results exceeded our expectations by far! 

Piotr’s strength increased by 5 kgs, which is almost a 6% improvement. What is also very interesting, Piotr managed to improve both his anaerobic and aerobic endurance significantly. His time under tension (TUT) for the 80% MVC-7 Repeaters on a 20 mm edge increased from 42 seconds at 68 kg to 60 seconds at 72 kg. The TUT at 45% MVC-7 increased from 341 seconds at 38 kg to 510 seconds at 41 kg.

After five months of training, Piotr continues to progress systematically. He also keeps relentlessly ticking-off more 5.13a/7c+ routes from his projects checklist. Piotr is now physically ready to tackle his 5.13b (8a) lead climbing projects. I’m keeping my fingers crossed in the hope that he will soon reach his personal best!

Hangboard Training Program – Sam

Samantha is a super experienced lead climber, who has traveled worldwide and climbed rocks on almost every continent. She likes climbing bouldery routes, with short cruxes and good rests in between, but since her aerobic endurance is excellent, she can comfortably project longer routes as well. 

Sam’s Critical Force to MVC-7 ratio is high, reaching almost 50% (Table 1), so it is no surprise that she established her 5.13b (8a) personal best in Red River Gorge [1]. Because of that, we decided to emphasize strength development, to help her improve on overhanging and powerful routes. Sam trained diligently throughout May and significantly improved her finger strength, strength endurance, and aerobic endurance, as can be seen in the progress plots below.

At the moment, Sam is climbing mainly outdoors, so we reduced the training volume accordingly, but strength training remains the cornerstone of her hangboard program.

Here's what Sam says about the Program:

When COVID hit, and all the gyms closed down, I knew I needed something more than the standard repeaters method that I had been doing on my hangboard for years. I took to the internet and was immediately overwhelmed by how much information was out there and the conflicting schools of thought. I am the type of person that works best when someone tells me exactly what I am supposed to do, but after spending a bunch of money on websites, books, and programs, all I had was a bunch of information to sort through and no detailed plan. I came across the StrengthClimbing website and was immediately drawn to how organized the information was and how thoroughly Jędrzej analyzed and explained various training methods. I messaged Jedzej to ask him about some of his research, and I was so impressed with how quickly he responded and the amount of information he provided. I have been training with him now for around 7 months. His programs are always so easy to follow and specifically designed for my needs and style of climbing. He is constantly communicating with me, tweaking my plans, reassessing, testing, and ensuring that I am on the right track. His programs range from complex to quite simple. If you have tons of time or barely any time at all, he will be able to find something that suits you. It's easy to remain motivated when I have someone to report to, and the programs switch frequently enough that I am never bored. If you want to get stronger and remain motivated, I strongly recommend training with Jędrzej

Hangboard Training Program – Daniele

Daniele is a powerful all-round climber who specializes in bouldering but is also successful in sport climbing. He’s had a great summer so far, and he managed to set personal bests in both bouldering and lead climbing. His most spectacular achievement in 2020 was climbing Souvenir 8A in Chironico, which was set by Fred Nicole [1]. Below you can see an example ascent video.  

Video 1: Example ascent video of Souvenir 8A.

Another success for Daniele this year was that he improved his personal best in sport climbing to 8a+ in August. Daniele prefers short and bouldery routes. When we look at his progress table, we can see that his Critical Force is currently 34% of his MVC-7, which is typical for boulderers. Still, because Daniele is very strong, his CF relative to bodyweight is 66%, which is definitely sufficient to send hard lead climbs. 

Focusing on improving his endurance would probably let Daniele reach 8b+ fairly quickly. However, since he has a preference for bouldering, we are emphasizing his finger strength development and working on his endurance as a secondary goal.

Here's what Daniele says about the Program:

''I guess every climber that wants to improve follows - or wants to follow - a training schedule. And I bet that every climber - at least once - has searched online for the best recipe, the magic potion that transforms you into a Beast (well, at least in my naivety, I'm still a little dreamy boy who's looking for that :). So one day, thirsty for new plans and exercises, I bumped into I started to read the articles, to feed the online tools with my data to discover MY GRADE (and I stop here, because this topic is an encyclopedia apart 🙂 and, when I reached the contact details...'I know this guy!'. I met Jędrzej back in 2009 in Gent, Belgium. I was there as a visiting student at the university. He was working on his PhD. We met at the local bouldering gym (''where else'', I would add :). Besides the regular climbing sessions, we enjoyed student life as well. After that year spent together, we somehow lost contact. But 1 minute after discovering his website, I wrote him a message, and we started to exchange opinions (mainly coming from him, due to his deep knowledge of the topic - while myself just random bits of it, mainly ''stealing'' :).Then I agreed - or probably I begged him, I don't remember - to be one of the 'guinea pigs' for the validation of his methods: really excited and curious to see if this new recipe was a real elixir. Well, after a few months, I climbed my highest bouldering AND sport climbing grades! I'm still following the training (which is not the same but fine-tuned by him from time to time), and I can't wait to see what it will bring! Anyway, when we first met, I immediately had a very good impression of him, mainly his scientific and detail-oriented mindset. So, I'm not surprised to see the quality of the results: a combination of the most efficient training methods out there, synthesized into specific training plans for your personal goal. All thanks to his dedication, based on accurate studies and researches moved by passion for the topic. I hope I have found my magic cocktail (too many ''unwanted'' references to drinking in these lines..anyway, I can't wait to crack open a beer with him again :)"
