Getting Started With Crossclimb
Crossclimb is a training framework and associated app ecosystem built around combining strength work with route-reading and mobility for climbers. It's not a game, it's not a gamified habit tracker, and it doesn't replace actual time on the wall. It's structured programming that tries to solve the problem most climbers hit after their first couple years: you know how to climb, but you don't know how to get stronger in a way that actually transfers to cruxes. I've used it for about eighteen months across two cycles. Here's how it works in practice and where it trips people up.What Crossclimb Actually Is
At its core, Crossclimb is periodized climbing-specific strength training. You pick a cycle length — usually four to eight weeks — and the app generates workouts based on your recent bouldering or lead grades. The algorithm weights finger strength, pull-to-push ratios, antagonist work, and mobility so you're not just doing more pull-ups until your elbows give out. The workouts break into three blocks per session: a primary strength movement (campus board, hangboard, or dynamic power work depending on the phase), a secondary accessory block, and a mobility or prehab section. Each session runs about forty-five to sixty minutes. You can do it three or four times a week alongside actual climbing.The app tracks your progression using RPE-based load management rather than strict percentage math. This matters because your max hang weight on a Tuesday might be different from your max hang weight on a Friday depending on sleep, stress, and how many routes you onsighted the day before. The app adjusts for that.
Setting Up Your First Cycle
Download the app and go through the onboarding. You'll do a fitness assessment that includes a max hang test, a pull-up max, a squat assessment, and a flexibility screen. Don't skip the onboarding tests just to get to the workouts faster. I've seen people do this and then program at intensities that wreck their tendons within three weeks. After the assessment, pick a goal block. The main categories are: - Base Phase — general strength and tendon prep. Four to six weeks. This is where you build the capacity to handle harder stuff later. - Specific Phase — finger strength and power work tied to your target grade range. Three to five weeks. - Peak Phase — maximal intensity, lower volume. One to two weeks right before your climbing trip or competition. Most people screw this up by jumping straight to the Specific Phase. Your tendons need twelve to sixteen weeks of base loading before they can handle heavy hangboard work. If you skip base, you're gambling with your elbows.Set your availability. If you can train three days a week, the app will give you full-body climbing strength sessions. Five days gets you a split routine with separate pull, push, and leg focus days. Anything less than three days a week and Crossclimb starts losing its effectiveness because the volume needed to drive adaptation just isn't there. Be honest about your schedule.
How a Typical Week Looks
Here's a realistic example from one of my base phase cycles. Monday is upper body push and pull with a focus on scapular control and finger strength at moderate loads. Wednesday is lower body and core — weighted squats, single-leg work, and anti-rotation core. Friday is the full climbing-specific session with hangboard repeaters and dynamic power drills. Saturday is open climbing or a light mobility session. The workouts themselves are straightforward. You show up, open the app, and it tells you what to do. There aren't hundreds of exercise variations. The app cycles through a fixed library and rotates exercises every two weeks to prevent overuse patterns. Each rep scheme comes with rest period recommendations and RPE targets.I once had a bug where the app wasn't recalculating my RPE scale after I upgraded my max hang from 20 kg to 25 kg. The subsequent workouts were programmed at intensities that felt completely wrong — like I was supposed to be at RPE 8 but the weights suggested RPE 5. I found this by cross-checking my actual perceived effort against the prescribed loads and noticed the mismatch. The workaround was going into settings, force-stopping the app, clearing the local cache, and re-syncing from the server. This reloaded the updated max values. It took about three minutes and the issue hasn't recurred since a patch went out a few weeks later. If you notice similar mismatches, don't just push through it. Check your max values in the profile section first.

Where It Actually Works and Where It Falls Apart
Crossclimb is genuinely useful if you're a recreational climber training two to four days a week who wants structure without hiring a coach. The programming is solid, the progressions are sensible, and the RPE-based approach prevents the classic mistake of training at too high an intensity for too long. For that population, it typically cuts down planning time from about two hours per week of spreadsheet work to maybe ten minutes of checking the app. The downsides are real though.The app assumes you have access to a hangboard and a pull-up bar. If you're training at a commercial gym that only has general fitness equipment and a bouldering wall, half the workouts are unusable. You can substitute exercises in some cases, but the substitutions aren't always well-mapped. A campus board protocol doesn't have a clean gym equivalent.
Another issue is the limited customization for specific climbing styles. If you're primarily a lead climber working on endurance, or primarily a competition climber doing benchmark problems, the default programming still skews toward bouldering-style power and finger strength. You can adjust, but you end up spending more time tweaking settings than just following the plan. The app also struggles with complex periodization needs. If you're peaking for a specific trip and need to deload in week three while ramping volume in weeks four and five, the standard cycle templates don't handle that kind of nuance well. You'd need to manually edit workouts or run two overlapping cycles, which gets messy.Practical Advice I Wish I'd Known Earlier
Don't treat the RPE targets as suggestions on weeks where you're traveling or heavily stressed at work. The app can't account for your life outside climbing. If you slept four hours and your job involves heavy lifting, drop the session to a maintenance level or skip it entirely. Consistency over six months beats intensity for three weeks. Track your sleep and stress lightly. Crossclimb's load management is decent but it's only as good as the input data. I started logging a simple one-to-five stress score each morning and the app's weekly load estimates became significantly more accurate after two weeks of feeding it that data. Use the mobility sections even when you want to skip them. This is the part everyone skips. The mobility work in Crossclimb is designed to counteract the specific tightness patterns that climbing creates — hip flexors, lats, thoracic spine. Skipping it doesn't hurt you immediately but six months in, you'll notice your foot placement precision degrading and your shoulder health getting achy. The mobility sessions are twenty minutes. They're not optional if you want longevity.If you hit a plateau after six to eight weeks, it's usually because you've been climbing at the same intensity on your open sessions while the app has been progressively overloading your strength work. The two can conflict. Either reduce your outdoor climbing volume during the heaviest training weeks, or accept that your strength gains will be slightly slower but your risk of overtraining drops considerably. I chose the latter approach and it worked better for me long-term.
