In reply to Flinticus:
With the proviso that I’m 38 I’d say you’re getting some solid advice here. The principles of training remain the same for any age - specificity, progressive overload combined with rest for compensation. That’s just basic sport science/ physiology to encourage adaptation. Age means that progress might be slower and the need for rest/ support activities might be increased, but there’s nothing stopping #gainz if you’ve got untapped potential in there. Make sure you’re eating and sleeping enough!
Just a note though - 7A is quite an abstract goal. I assume we’re referring to outdoor problems here. Do you want to climb *a* 7A or have a good chance of getting up *any* 7A?
If the former, then to me it’s all about having a project (or couple of) in mind that inspires you, are accessible (e.g. drive time/ walk in time/ long condition window/ safe to climb if not able to get a spotter etc) and then just working towards it. The problem itself will then tell you what you need to do depending on where you’re struggling.
If the latter, that’s about bringing up general level and will require a broader approach e.g. working weaknesses/ blocs of training for strength/ power/ power endurance endurance/ consistent improvement on flexibility etc.
Overall, for bouldering, my main improvements have come from 1. A structured and continual fingerboard programme to isolate and strengthen components of fitness + manage injuries (your shoulder injury - could this be rehabbed and strengthened using a fingerboard programme?) 2. Having access to a woody for power/ power endurance training 3. Being inspired and motivated with projects in mind.
edit - just re read that you have no home equipment and minimal time. My advice is to get a decent wooden fingerboard (I’ve got a BM2000 - lovely board but I reckon a 1000 probably gives more options) and commit to using it. Relatively cheap, very accessible and you can get a good session in even with only 30-60 minutes. Can work individual grip type strength/ shoulder strength/ endurance/ some power (velocity pulls etc.)
1 more edit just to emphasise that all this physical/ training stuff is actually probably secondary to tine on the rock!
