I know I have to tweak my workout schedule but here it is. I've only been doing this particular schedule for about two weeks.
Tuesday: 35-40 min HIIT on treadmill
I do a 5 minute warmup and then run at about 9.0 for a minute and then walk at 3.9 for 1 1/2 min. I repeat this about 8 times.
I work my legs for about 45 minutes. I do squats: 4 sets of 8 with the machine. Lunges: 3 sets of 10 for each leg with dumbbells Squats: 4 sets of 10 with dumbbells. And some other machine that works the front of the legs (don't know what it's called)
Thursday: 35-40 min HIIT on Treadmill
I do an ab workout for about 15 minutes and I do two machines that work the chest. I don't really focus on my arms because they are already defined. Maybe this is a mistake.
Saturday: 35-40 mins on treadmill with incline at 8.0 and mph=4.0
Ab workout
My schedule is extremely hectic. I work nine hours a day, I am the co-owner of a small business, I write grants on the side and I have a three year old that keeps me extremely busy so these three days are the only time I can make it to the gym. I go at night around 8:00 or 9:00. I know for a fact I could do more weight training because I want bulk and definition but I'm not really knowledgable in this area.[/QUOTE]
Just thought I would ask...are you doing the cardio right before your weight training? I do the opposite. I do the cardio after the weight training on days when I can't do it in the morning on an empty stomach.
You mentioned abs--seeing those are mostly about the diet; however, I thought I should add that a nice set of abs come from training them with weight. You didn't realize specify what your 15 minute ab workout was. I do hanging leg raises, rope crunches, and crunches with a medicine ball, for example. I train them like any other bodypart. My abs show all the time at 20% bodyfat...so they are pretty developed.
The rest of your training, could use just a little tweaking...I'm sure the more knowledgeable ladies on this board could help you out there. I've been training for 11 years (on and off) and am kinda stuck in my ways.
I train 6 days a week and dedicate each day to a different bodypart. Like this:
day 1:chest/cardio
day 2:back/cardio
day 3:hams/abs
day 4:shoulders/cardio
day 5:arms/calves/cardio
day 6:quads
day off.
One way you could break it up would be like this:
Training day #1: Chest/Triceps/abs/
Training day #2: Back/Biceps/calves
Training day #3: Shoulders/Traps/legs
Not sure how you would do cardio on day three...I can't do shit after I train legs!
But, there are many different and effective training splits. Maybe someone who trains on a three day split can post a workout for you.
Good luck and I hope you reach all your goals!
