    Should You Workout When You're Sick?

    Is this workout routine outdated

    Definitely not outdated man. The biggest thing you could do is to modify the actual exercises you do each day. Let's say you are on Chest and you usually use a barbell. Switch it up to dumbells for a few weeks. Then maybe switch it to bodyweight for a week, then back to barbell for a few weeks...
