    I've been training at CrossFit Lawrence for 4 months now and the progression of my fitness level is…read morenothing short of amazing. Were it not for the incredible coaching skills and encouragement from trainers Thomas, Kyle and Andrew, I would not have found my love for powerlifting and be preparing for my first competition. If you want hands-on attention and training without the cost of a personal trainer, this is the place for you. Their focus on education and injury prevention is top-notch, their approach truly comprehensive. They even have kids crossfit, crossfit masters (ages 50+), and crossfit moms (pre- and post-natal) classes! Thanks to CFL, I can now do things which I never thought I'd do - Olympic lifting, powerlifting, unassisted pull-ups, dozens and dozens of push-ups, handstands, gymnastics, running 7 minute miles, etc. My level of fitness has never been higher and there's plenty of room for growth and improvement. The facility at 22nd & Haskell is roomy and the walls are covered in striking street-style graffiti. It might not seem a place where you would find yourself, but once you're there it feels like home. There's a great sense of camaraderie and support among the CFL members. Everyone encourages each other to keep going, to work hard, and congratulates each other on a good workout. It's rare to find such a good group of folks who have nothing but truly and sincerely nice things to say about each other. If you want to take your fitness to the next level, enjoy your workouts and meet some great people, this is the place for you. I, for one, will be happy to make your acquaintance.

    I have been training at CFL's temporary location on and off for about 18 months now. Having just…read moreannounced acquisition of permanent facilities here in Lawrence, CFL promises to become the premier spot for fitness and performance training in town. Thomas, Kyle, and Andrew are fantastic coaches, incorporating contagious enthusiasm and energy with the Crossfit methodology and up-to-date certification and education. Membership at CFL is mostly young 20-somethings, but there is also a strong core of more mature athletes and athletes-in-training. Regardless, everyone I've met there has been friendly, supportive, and excited. If you are inexperienced with Crossfit, expect a friendly welcome, and be ready to jump into the most efficient training program I have encountered. For visiting Crossfitters, come grab a WoD and make some new friends!

    I called ASI one day out of curiosity. I had been group training consistently elsewhere for a…read morecouple of years and was looking for a more tailored approach. Chris Dellasega (owner) answered the call and I immediately recognized a level of professionalism, focus and knowledge unparalleled in my experiences so far. Chris was able to assess and build a program to strengthen my weak points and propel all of my PR's to new heights. Every time I reach out with questions he has prompt, concise and effective answers. His programming has eliminated chronic pains I've dealt with for almost 15years. Particularly hip and low back pain using split squats. His prescription of external rotation exercises fixed a shoulder I've been struggling with for over 8 years. I've now been training and learning from Chris for almost a year and I'm feeling stronger and healthier at 32 than any other point in my life. If you're looking for a $10 membership at a corporate gym (with $10 results) to check a box on the list, you'll want to go elsewhere. If you're looking for a tailored effective plan to get healthy, strong or hit new goals in any sport, look no further.

    I left Genesis due to the cold, impersonal, money-grabbing nature of the gym. When Genesis took…read moreover from LAC, I was appalled at how they treated the LAC workers and eventually was able to seemingly push most of them out by offering less than inadequate contracts. Unfortunately, the best trainers in town left the gym, and Genesis now employs far inferior, corporate-controlled trainers and cold, impersonal front desk personnel. They all look good in their preppy Genesis polo shirts, so I guess that's what counts. Unfortunate! So I decided to take a look at Athletic Strength Institute. I would encourage everyone who belongs to Genesis to drop your membership and come check out ASI. The owner makes you feel welcome. He is knowledgeable, motivating, and plans individual workouts to fit each of his client's needs. It may not be the biggest gym in town in terms of square footage, but it is the best in terms of what really counts... results.
