It depends. There are certain aspects that you can treat like you do grocery shopping. Weight training, for example. Three sets for three exercises three times a week, with five minutes rest between sets. Bring a book, set a timer. When the timer goes off, you spend less than a minute doing the set, and then go back to reading. Once you've done squats, deadlifts, and the like for a few months you can focus on your form without losing the context of the book. For rock climbing, is there anything else you need to do in that direction so you can climb once a week? You can also try to add loads back to your life elsewhere. Where can you replace sitting down with squatting, machines with lifting, and car trips with walking or cycling without compromising your time? Can you put rings or a bar by your workstation so when you pause to thing you can reach up and hang? Katie Bowman is a wonderful person to read on the topic of adaptation to loads.
