Chris over at
In his next training phase, Chris is planning on working on some sort of running activity two days per week. He is not sure yet what his lifting routine on the other days are going to be quite yet. In the past, Chris has tried and bringing his body fat percentage down. I think that the best thing that Chris can do right now is interval work.
Depending upon his lifting schedule and if he is planning on running twice per week, Chris could go on a 3 day / 4 day split (for example, Monday/Thursday or Saturday/Tuesday) or he could go on a 2 day / 5 day split (Monday/Wednesday or Tuesday/Thursday, for example). I think that if he is on a 3/4 split, then he should be doing 2 interval sessions per week. I recommend that he go on a 2/5 split, though, and only run intervals on the first workout of the week and then run easy two days later. This would give him a chance to stretch his legs out shortly after his interval work, and will help keep him healthy and injury free.
For intervals, I would start at half mile repeats. Chris will probably want to start at 2 repeats per workout at around 3:30 to 4:00 minute pace with 90 seconds to two minutes of rest. Depending upon how tough of a workout that feels, he should do the same workout the second week or add another repeat to run 3 of them. I think that he should keep that up until he feels completely comfortable doing that, and then try running them faster until he can run between 3:00 and 3:15 for 3 repeats.
It would not be in Chris’s best interest to try running them faster or running more volume until this workout became easy. By that point, he should have spent one of his weeks with another mile time trial and be at least 4 or 5 weeks into his interval training. As it becomes comfortable and fits into his lifting schedule, Chris should start running an extra interval every week or two and may want to start experimenting with running them a little quicker. The week before he does his mile time trial every month, he should cut back and only run 3 repeats.
Every interval workout should be preceded and followed by a warm up and cool down that is at least 5 minutes but preferably 10 minutes long. This can be walking or slow jogging, but there should be at least a little bit of slow jogging for the last couple of minutes of the warm up and the first couple of minutes of the cool down. Stretching is optional; I would only do light stretching before the interval work and save any heavy stretching for after the cool down when it will do the most good.
If Chris decides to opt for a day where he does some light running each week, then he should start by jogging a mile or two at a slow pace. If he is running two interval sessions per week, then he should consider running a longer warm up on the session with the fewer days of rest and should run 1 less repeat than he did in the previous workout (unless he did 2 repeats, in which case he should still run 2).
Given this modest program and Chris’s goals, I think that he could do this work and make not only his 6:52 goal but his 6:12 sub goal after a few months. His body is not used to doing this sort of work and will respond quickly to it.
