We love Iron Impact. Lillian is great! She is very good with my 13 year old daughter who is gaining confidence and skills that will help her in life. I am more at ease that my child is gaining real world self defense skills. Less

I have been training at Iron Impact Knoxville for several months. The instruction is top notch for students of all experience levels. The instructor has the ability to describe complex movements in ways that everyone can understand. The learning environment is respectful and inclusive for all the participants. Everyone is challenged and encouraged to do their best. The training is relevant and can prepare you to react appropriately to hostile situations. I would personally recommend Iron Impact Knoxville to anyone as it is a great workout, fun, and the training can possibly keep you safe from a dangerous situation. Less

Lillian Lim is an excellent teacher, balancing the needs of the newer students with those that have been there longer. The classes are a perfect blend of conditioning and self-defense, which is perfect for being ready for an attack. Highly recommend. Less

I took my first of Lillian's beginner self defense class last eve. She made everyone feel comfortable and is very encouraging as well as it just being fun. I'm looking forward to learning more and growing in my skills to be able to protect myself if needed. Highly recommend. Less

Lillian is the best! She’s super understanding and works well with your schedule and your ability to do/not do things. She really has your best interests at heart! Less

I can't say enough about personal trainer Lillian Lim at Iron Impact Knoxville! I had a 2nd session with her & was very impresssed! She looks at your needs - where you are & where you'd like to be - and tailors your workout. If you're looking for martial arts, personal training, or self-defense (I had no idea the huge need there is for this!) you owe it to yourself to check her out!! Less

Lily is the best trainer I have ever had. She is very passionate about making you confident and strong. I highly recommend her to anybody who want to make a difference in life. Knoxville is lucky to have such professional trainer like her. Less

Lillian is an amazing trainer and motivater. I've been having Lower back and leg issues. She tailored our training session to help me quickly adjust my fitness needs. I feel stronger and pain free with her guidance and support. All this in only one month time. Can't wait to see what the future holds. My mobility and strength is gradually coming back. I highly recommend her. Less
