I've been hitting the gym on Sunday afternoons as well.

Leg press alternating with pull ups
Squats
Deadlifts
Upper body stuff. I generally shoot for two back, two shoulder and two chest work outs, such as bench press, incline bench, decline bench, flys, back flys, seated cable rows, upright rows, military press....
Prone Leg Curls single legged.

I also mix in a bunch of hip flexor, abductor and inductor workouts given to me by my physical therapist. I avoid leg extensions as the PT said she is concerned they would put too much strain on my knee and the still healing tendons.

I'm slowing building up the weights with the lower body stuff trying to build more strength and mass. My upper body stuff tends to be a bit less intense.

On most Mondays, I'm a bit stiff. Tuesdays are worse, but I get on the trainer on Tuesday nights for 1.5-2 hours of spinning/cadence drills and that starts to loosen things up.
