Time for a change?

My diet has been at 11'x BW 20/40/40 since Feb 6th (4 weeks), and here are my workouts from this past week:

3/6 AM - Shoulders at hotel, run outside 48 min HR 140-150
PM - 30 min HIIT (10 on treadmill, 20 on elliptical), 20 min elliptical with HR at 150 avg
3/5 REST DAY
3/4 - Biceps, Triceps, Abs; 20 min HIIT on stepmill, 10 min @ 155 HR (tired due to time change and work schedule)
3/3 - Glutes/Hams; HIIT 10 min on treadmill; 40 min on elliptical with HR 150-160
3/2 - Back; elliptical 30 min HR avg 150, swim 30 min
