To have great abs, like California Bay area Personal trainer  Stephanie, of Los Gatos and San Jose California  pictured here,  Houston Personal Trainers say a person must to burn fat. By replacing one pound of body fat with sleek muscle, the metabolism speeds up and additional  calories are burned every day and fitness improves. To burn fat and build muscle do this advanced workout designed by Houston Personal trainer Melissa at Citiflex:(yes this IS an AB workout..remember to get Abs, a person needs to do a lot of cardio.)
Monday, Wednesday and Friday Run fast Sprints and then jog...sprint for three minutes..jog for five minutes..and repeat...make the workout last for an hour and make sure to have a warm up and cool down period. Advanced fitness personal training clients near Memorial Park or Downtown Houston can do the sprints up an incline or hill.
Tuesday, Thursday and Saturday do the following five part workout: yes this IS for ABDOMINALS!  =) NO hills needed for this part..anyone in Tomball, Spring, 1960 Area, Kingwood, The Woodlands or Downtown Houston can do this!

San Jose personal training workout part one: three sets of squat jumps, ten reps each set.
San Jose personal training workout part two: three sets of lunges holding eight pound weights in each hand, twenty lunges each set. In between each lunge do a shoulder press holding the weight.
San Jose personal training workout part three: three sets of pullups  hanging from a bar with body weight, ten reps each set.. a chair under the bar may be used for assistance.
San Jose personal training workout part four: two sets of jumping pushups(do it just like it sounds, do a pushup and then jump up, back to a pushup etc.), ten reps each set. 
San Jose personal training workout part five: three sets of dot drills.. hop by changing directions in a repeating pattern on the floor using tape to mark five dots on the floor in a square, with one dot in the middle. Each set of dot drills should have thirty reps. Houston fitness freaks can do this timed with a stopwatch and try to beat the time every set.
Do this very difficult and intense but very effective workout recommended by Houston and TheWoodlands Personal Trainer Melissa, for very fit individuals who want to have ripped abs. Keep the workout going for six weeks and eat a twelve hundred calorie a day meal program which includes at least five servings of veggies and 1/2 ounce of water for every pound of body weight, and watch the abs get cut.http://www.youtube.com/watch?v=i7LpZkq0tQU  This youtube video has chest and back workout to go with the abs workout. check it out.
