Hello, More than 15y ago or so I was deeply into weight training and the few last years of that going with HST after it became public. I was pretty big and also strong that time. Later I lost interest and got more into biking, job & family etc. I am 44y now and figured that I gained too much belly and of course lost muscle. So begin of Jan I pulled my old food scale and caliper out of the drawer and started to cut to see how it goes. By today I lost 6..7Kg and feel I want to go at least 4..5Kg further to end up somewhre around 15% BF hopefully. For now I just kept cycling but did not start any weight training yet. But meanwhile I convinced myself that I probably should and started to check out what's the trend today. I somehow fully expected that the whole world must be applying HST by today, but after a few hours on YT and the web ...what I surprise. I found and interview with Bryan from 2018 or so by specifically googling for it and that was it Anywas, to not bore you too much, I have one doubt I wanted to clear: The advised principles from back in the days didn't seem to have changed. Its all still about frequent & progressing mechanical load. So muscles grow bigger while becoming more resistant towards the applied load at the same time. So I wonder whats the best tactics during my significant kcal deficit and fully decondtioned muscles? I could a) start weight training right now. That would probably help to prevent further loss of lean mass, especially towards the later phase of the diet. On the other hand, I think that I would condition my muscles (ie. making them resistant against load) in a situation where they can't really grow due to kcal restriction. That feels like a "waste of load" in some way. or b) finish the diet without weight training and accept a greater loss of mean mass. But after, when I start loading my muscle tissue, all the load increment can be turned into actual grow, as I will not be in a caloric deficit any more. I think if I would put this up as a vote in any BB forum, I'd get 99.9% for a). But please try to understand the argument I am trying to make. Once one has adapted to a certain load A, there is no going back. So if that load A has not resulted in hypertrophy, once needs to rely on higher load for that prupose later. But we all know that the load you can generate is limited. Ie. weights used can't be increased indefinitely. Thanks for your thoughts on this!
