I decided a 2 weeks ago to go back to SSB1MV with everyone having to stay indoors. With all the free time I’ve got now, I figured why not add some low intensity volume. I think I’m going to add 30 mins of Z2 (65%) at the end of every workout. This would be an extra 110TSS per week. Does anyone think this would be too much stress? I’ve been through a TR build phase before with up to 500 TSS per week, it was tough, but manageable.
