I love internal workouts because I don’t like to be bored! I love jumping from thing to thing. It gives me the best workout because I don’t slack from boredom 🙂 -Samantha
Love your workouts! Would love to have a Gymboss!!
Interval workouts are what gets my butt out of bed before a busy day of work and busy evening with kids. Your interval workouts captured my attention before Christmas (2013) and have got me pumped to check the site every morning and night to see what my next workout is going to look like. Not only have the workouts held my interest but the results I’m seeing are AMAZING! Thanks for your commitment to all us people who love to workout from home.
I love interval workouts, because it’s a quick and effective way to get my workout in and burn a good amount of calories. I also love that you can adjust your rests periods, but I love a short rest for the extra burn!
Interval workouts are awesome because they cause great calorie burn during and after the workout, they are fast, they get my heart rate up quickly, and most of all, they are SUPER FUN! Thanks Melissa!
I love interval workouts because this is the best way to get in shape.
These work out tricks and tips are the best ways to reduce the tummy. But people still find tummy tuck surgery the most easy and convenient way to cut off the extra fat on their body. I found this post quite informative! 🙂
Looks like there are good apps for the phone like the gymboss. Can you recommend any?
I love interval training because they are always different and each interval is short so I can push myself knowing the pain will be over soon!
Intervals are great because it changes up the work out routine and gives easy goals to attain. At least for me 🙂
Intervals are quick, short and intense!!!!!!!

I always work up a good sweat with your workouts. Thank you so much for posting them and sharing with us, and for the chance to win an interval timer!
I’m a morning workout person and don’t always have a lot of time, and yours were the first interval workouts i discovered almost 2 years ago. i’ve been hooked ever since! you’ve also inspired me to search for even more interval and HIIT workouts, and create my own, to increase my stash of workouts to choose from– keeping things varied means i’m always challenging myself! thank you!
I appreciate that you take the time out of the day to keep your blog fresh and up-to-date. I’m usually an avid gym-goer, but recently, it’s been feeling like old news. I enjoy your home-workout training method and I feel like I’ve been getting greater, more realistic and transferable to day-to-day life results by exercising outside of the gym! Thanks, Melissa!

I LOVE, LOVE, LOVE interval workouts. I’ve tried everything and interval workouts give me the most bang for the buck. I love your workouts because they’re always different. Keeps my muscles guessing.

I love interval workouts because they’re efficient! As a mom of a toddler it’s hard to find an hour to workout, but 20 minutes is very possible!
With three young kids, and a running workout most days, interval workouts like this are the only way I can imagine getting such awesome cross training done! Thanks!
I discovered your free workouts towards the end of last year as I was looking for workouts that was challenging but doable and yours were some of the best so far. I’ve been following your workout since and I’m loving it! I love the fact that it’s short and I can incorporate it in my busy day. I love interval workouts because it’s quick, I can repeat it as much as I want or add in another interval from a different workout. I love the fact that you break it down so well for us to follow. Thank you!

Love your workouts! They are really helping me get back in shape after having 2 kids!!
I love interval training because with them u can reach the maximum burn in a short time as opposed to training for hours at your pace. I always push myself very hard within each interval, having timer I am more disciplined and take rest only when my 10 seconds is up. NO slacking in between. Last and not least I love the sweaty beast I am afterwards these interval workouts. Oh, and there is no better sound to my ear then the last beep, ding dong sound or her saying workout complete, I feel like I can conquer the world.
love interval training because they are intense, fun and keep me focused, after I own the HIIT for my agility, strength and endurance.

I love interval training because I always feel like I can commit to 15 minutes! I usually feel so great after one round that I end up doing more.
I love interval training because just when you think you can’t move a muscle, you get a short rest, then start again with more gusto!!
I actually prefer interval training because I can get my fitness on in a shorter amount of time so I can get to things I truly enjoy like eating!-:) Thank you so much Melissa!
I love HiiT since it is quick and intense. I always feel strong and accomplished when done since some of your moves are amazingly different, effective and challenging to the max! Thank you for continuously sharing your passion for fitness with others.
Internal training is my favorite when focusing on strenght training. I like to spend most of my time running when I exercise, however, I know I need strength training to remain injury free. Interval training has been effective in getting the job done. 🙂
Interval training is a great way for me to fit in short but effective workouts when I get home from a 12-hour work day!! I have come to enjoy them even on my days off because they are so much more effective than spending an hour in the gym! 🙂
I just recently started a boot-camp training and I’ve started to love HIIT training so much! This tool would really help me to keep doing them at home after I’m done with my training. Love your vids and workouts…keep them coming, Melissa! 😉
Hi Melissa, my first comment didn’t post – so trying again. I’ve run marathons and an ultramarathon in the past – lots of LONG SLOW miles. Then I started working out with you a year and a half ago and am now in the best shape of my life. HIIT workouts are amazing because they’re fun, fast, and challenging! I’m focusing more on speed in my running these days too, and am using interval training. Thanks for sharing your videos, you’re such an inspiration to me! -Melissa J.
I have been following you for a little over a year now. I really enjoy working out with you from day to day it keeps me motivated to stay in shape. Thank you very much for all that you do. x
