My APFT is coming up in April; I'm planning on working out 6 days of the week instead of my usual 5 (3 days strength, 4 cardio). Is that ok?

PFC Justin Bailey,
No, I would not recommend that as you are opening yourself up to injury. Your muscles need time to recover. What works for me may not work for you, but try this: Gradually increase your runs(outdoors on no-rainy days and on graded surfaces) to 5 miles every other day at a minimum. Also, do the same for your weights/muscle endurance or muscle confusion days. Take the weekend off, except I usually do a 3 mile brisk walk on Saturday and Sunday as well. These steps work for my Soldiers and I and we do very well on APFT day. Anyway, hope I’ve been of some help.

OK, I am a lot older, but my advice is to listen to what your body tells you. If you are over training, it should be easy to figure out. If you aren't getting the results you want, back off a bit. Muscles require recovery time and if you aren't getting the improvements, you are probably not giving them enough recovery time.

Every day should have a little cardio type activity. You don't have to kill yourself, but a little cadio should always be a part of the routine. Strength and what not is all well and good but the key to an old fashion APFT (PU, SU, 2M) is cardio endurance and muscle memory. You can bench all the weight that you want but that doesn't mean that you will max your PU.
