Cardio and shoulders

Cardio today for 30 minutes. Level 10 incline at 4.0mph. Burned approx 300 calories.

Following the cardio workout I did the following shoulder workout:

Shoulder press ( 35, 45 and 55lb dumbells) 10 reps x3 sets

Front shoulder raises (15lbs) 10 reps x3 sets

Side shoulder raises (15lbs) 10 reps x3 sets

Shoulder shruggs (75lbs) 10 reps x3sets

Reverse butterflies (70lbs) 10 reps x3 sets

After my shoulder workout I did approx 5 minutes of stretching to relieve any muscle aches. I contemplated doing abdominal workout before leaving the gym but I have been hitting abs pretty hard in the last few days so I omitted this from my workout today.
