I would hold that for about 4wks and then slowly start adding in push ups, sit ups, squats, burpee’s etc between the reps.
Depending on your work roster, ie, 4 days on 4 days off 12 hr days?? You could do 1000m on work days, and work up to 2000m on non days.
So instead of 8wks to get there, it might take 12wks?
The Q. you have to believe in is - Is it worth it? How much time do you have available and how much Better / Faster do you want to get? The answer to these Q’s will decide your volume
