Sports Medicine major here, I'd like to lend a hand.

Although compound lifts with weights are great, conventional body weight exercises are still superior for the non-elite athlete. This is what I suggest...

Upper body - Pushups for outward build and pullups for lateral build
Core - Planks and leg lifts (Also agility sports like Basketball/American Football/Soccer(Futbol) are amazing)
Legs - Squats and Lunges (Weighted if you're any sort of veteran)

The body needs to be confused and challenged, so maybe these few weeks away from the gym will be a good change.
