OK, I was on vacation for a week. Ate OK and did pushups, sit ups, pull ups, squats, lunges etc. While certainly not a replacement for a gym, it was the best I could do. My regular program uses the push-pull system. Instead of doing arms one day, back the next, etc, I group my exercises by movement. So I do chest, tricep, and certain shoulder muscles on Push days and Lats, biceps, traps, lumbar, etc on my pull days. On some of my workouts I focus more on core area muscles more (like chest and lats) and others I focus more on extremities (tri's and bi's). Anyway, that's just for clarification. On Tuesday, I lifted at the gym for the first time since coming back from vacation. It was a "Pull" workout (Pull ups, rows, deadlifts, curls, etc.) My strength was pretty well maintained, and I even increased my max deadlift by 10 pounds. Cool. Today, I did a "Push" workout (Various types of bench press, shoulder press, push ups, etc.) I had lost TONS of strength since last time I had a good gym workout. This is not the first time this has happened. This is the core of my problem: I have trouble retaining my strength in many "pushing" exercises, especially the bench press. Why is this and how can I prevent it? It really frustrates me when I have to spend a week or two just getting back to where I was before vacation.
