Full time job, three kids, wife seems happy (well, she works strange shifts in a hospital).
Despite this:
however, I don’t have any other hobbies. Actually, I’m not interested in anything else. Being super flexible and willing to leave the comfort zone is key. And the special circumstances of my job (virtual office, project driven). And I’m not interested in a corporate career. Wife has a good job, I have a good job. No need to climb the ladder.
Two-a-days is a great way to build slowly volume. Runners do this all the time, otherwise they couldn’t handle the volume.
But I consider it even extremely helpful for more experienced athletes.
Apart from this, if you have the time but can’t handle the volume: slow down. really slow down. do long rides in zone 1/2. And build from this.
