What's your opinion of HIIT vs steady state cardio? Why would you do one over the other and what time of the day do you believe is optimal?

How important is or how important do you feel is stretching before, during, during sets or post workout?

I want to maximize fat loss and I know Tabata is equal to a much longer amount of steady state, so I would prefer to do this style of cardio, but how many Tabata sessions are too much? Any recommendations for cardio programming?

I had a personal training class this past semester at school where time under tension was the main focus. My professor, a former strength and conditioning coach said that time under tension is best way to promote muscle growth. I was curious as to whether or not time under tension is as important as he and many others seem to claim.

what is your preferred exercises to train your abs? Also how  frequent should you train your abs? Lastly if your at a low body fat (sub 8%) and have a good 6 pack, do you think it's better to focus on other lagging body parts rather than spend more time on training your abs if you are pressed for time? 

What's your opinion on training muscles more than once per week? Can this be effective for bringing up lagging body parts? Do you think this can potentially lead to overtraining?

Hi Marc I am 50 years old and I have never been that active. I am overweight and I want to get in better shape so I can live a longer life and be able to do physical things humans were meant to do. I have a desk job and work 50-55 hours a week. I want to join a gym but I don't know how to workout. Or how to start... I don't want to be one of those people, who just goes to the gym and walks on the treadmill for hours. Any advice you could give me would be much appreciated 

hey Marc!  So I joined a gym and I'm looking into getting a personal trainer. Because I have no clue how to workout. My question is.. i have heard a lot about how some personal trainers just give their clients some cookie cutter programs that make some end up getting me hurt or end up hating training. Do you have any tips you could give me on what I should look for in a trainer? Or how to tell if they actually know what there doing?

what is the best muscle split for the best muscle growth results (when training 5 days a week)?

Hey Marc, 

I'm wondering if it matters how long you run the same program. Does your body get used to doing the same movements every training session and, in turn, muscle growth is stunted? I'm curious how often training should be changed up. Thanks, Marc!
