My time here at the 2 day kettlebell certification seminar was very inspiring. I have discovered things I didn’t realize I can do and things I’ve done that can be improved for better performance. The lessons where great and very knowledgeable and the hands on experience was phenomenal. Thank Greg!

Your kettlebell seminar was extremely informative for me in learning proper technique for using kettlebells. I feel like I learned so much and it was so much fun! It was great getting the hands on experience for all exercises exhibited. It is also great leaving with a package full of information for reference. Thank you!

Your kettlebell seminar was awesome! I particularly liked your in-depth detailed explanation and written examples of kettlebell program design for all levels.

Greg’s program designs and explanations were very detailed and yet easy to follow and comprehend. I look forward to teaching these training methods to my clients. Thanks Greg.

This was my 4th kettlebell seminar with Greg and it was excellent as always! Greg is very knowledgeable in his field. There is always more then enough information and Greg explains everything very clearly. Thank you Greg, can’t wait until the next seminar!

Greg’s seminar more than exceeded my expectations. His professional instruction went far beyond merely tossing around a kettlebell and moving your body through space. Highlights for me where client assessment and corrective strategies for all bodyweight and kettlebell movements. It’s amazing how much material we covered in just two days! I left the seminar with the out-most respect for Greg’s mental and physical powers. The knowledge gained from the seminar far outweighs the seminar investment.

After participating in Greg’s Underground kettlebell seminar and getting certified my training has changed completely. I went from outdated bodybuilding routines that resulted in many injuries to functional training with kettlebells and bodyweight –superbly effective and so much more fun! Greg teaches a solid system of physical conditioning that leaves no stones unturned. Not long after the cert seminar I got hired by a premier personal training facility in NYC. With my kettlebell and bodyweight training knowledge that stands out so much from the same old stuff that the other trainers are doing my personal training schedule got filed up in just a few weeks! My clients love the exciting and challenging kettlebell routines I come up with for them and cannot wait for more! Thank you Greg, I appreciate the jump start in the industry and looking forward to advance further in Compound Conditioning system. It works!

I had the opportunity to attend Greg’s kettlebell seminar a few years ago. Awesome content and he is an amazing teacher and it was totally worth the drive from tropical Cleveland Ohio!

Greg, Just wanted to thank you again for a great seminar this weekend. Your presentation was more in depth than I had expected. I can’t stop going over my notes – they’re a great value to my current personal training studies. Among other things, I really uncovered weaknesses my current training had kept hidden. I look forward to shoring up those loose ends and progressing my own abilities. My current schedule is pretty busy and I’m an hour a way from your gym, but I hope to make time for a few private sessions with you some time in the near future. Again, thanks for a stellar weekend.

Hi Greg, Just wanted to thank you for Saturday’s kettlebell workshop. I had a great time and I learned a lot. See you soon.

The Russian Martial Arts workshop was outstanding! As a trainer,I am continually looking for information to add to my repertoire. Today was an amazing day for that. Not only was the info amazing, but Greg’s method of conveying that info is second to none when it comes to RMA! Thank you Greg!

Greg’s RMA seminar was awesome; I know I can take this material to my gym immediately. The principles that we covered will definitely take my fighting game to he next level.

The Combat Systema workshop was amazing!!! Greg has tons of knowledge in areas of Combat Sports, Fitness, and wellness. He really helped me become a much better fighter, athlete, trainer and teacher!

As usual, Greg’s seminar surpassed my expectations. I’ve been to a number of Russian Martial Arts seminars, which were much longer, but have newer left with so much usable information! Greg’s unique ability to teach complex material with simple, understandable, and absorbable instruction is a breath of fresh air!

Greg, thank you for the eye opening experience in RMA! The knowledge you have is infinite. The passion you have for the art shows in your teaching. Instead of showing how great you are you make sure who you teaching understand what you are teaching. Thanks for all the help you have given me in just 5 hours!

Nice Russian Martial Arts seminar, Greg. Good level of explanation of techniques involved. Lots of personal attention to everyone. Very good correcting exercises, to combat techniques in the beginning. Looking forward to future training events!

This workshop on Russian Martial Arts exceeded all my expectations. I learned various techniques + principles that I could apply to my current training both in martial arts + fitness. I definitely plan to come again for additional training. Thank you again!

This weightlifting workshop was very helpful. My technique has dramatically improved from just morning! I could only imagine how I’ll look and feel after using the program for a few months. My favorite thing about the class was how easy it was to understand the insructions explained and implementing them into my own lifts. I had a great time! !

I thought your Olympic weightlifting workshop was great and I learned a lot. Teaching was great and I had a lot of fun. The instructions were very detailed and precise. Awesome experience!

The Olympic Weightlifting workshop was great! I haven’t really had time to actually break down most of the workouts so this was worth coming to. I liked how you showed others ways to involve bands and other tools to work on form and everything else. If there is any other levels I would be glad to attend. Thank you!

Overall, seminar about what I expected. Great explanation of fundamentals of Olympic lifts. Cost/value was appropriate. Sample training program is a very good starting point as a follow up. Will consider returning for future seminars 🙂

I really enjoyed the workshop. I felt I gained a valuable tips on technique relating to Olympic lifts. Some of the progression ideas were really useful, in addition will be able to be used moving forward. I loved the band use for squat tension. It will be very helpful in progressing to deeper more stable squats.

I thought your Olympic Weightlifting Workshop was really good. I learned so much. I liked that you covered so much and you went deep into the exercises. You teach me a lot. I’ll be back! 😉

Greg’s handgun course was great! I have learned a lot! This was my first time holding real gun and participating in this kind of seminar. Very informative and eye opening information. I’m very happy that I was able to participate in such high level of training from the very beginning. Thank you!

I learned more about tactical/combat Handgun Deployment in 3 hours of Greg’s class at Underground gym then 13 weeks I spent in Police Academy!

Thanks for a great handgun workshop. It helped open my eyes to the knowledge that can be learned. This class was just a start. Much learning to come. Thanks.

Superb Tactical Handgun seminar! As always, Greg’s skill + attention to detail allows participants to explore + understood as opposed to just following. If you get the opportunity to train w/ Greg at the Underground Gym, give yourself the gift of knowledge as well as security.

The training I have received from Greg and the Underground Gym team has been above par in all aspects. I have never left a session with regret! In regards to my firearms training, Greg has been with me every step of the way. Dealing with a firearm definitely brings nerves and apprehension to the forefront, but Greg’s expertise and reassuring demeanor sets the nerves aside and creates an environment that allows the student to learn without fear. Greg helped me from the very beginning, from choosing the best firearm for me, to learning how to shoot it for the first time, to running real life scenario drills with live ammo. He is truly a one of a kind Master that has made me feel safe and confident in my abilities to handle my firearm in any situation.

Greg is very Knowledgeable in the subject of gun safety and use. His class consisted of the essential skills needed if you safely want to become a gun owner. His tactics are very sensible and useful in real life situations. Very well run class from set up to information and instruction. !
