8th Day Crossfit Gym is hands down the best place in Grand Rapids for those interested in getting in shape or becoming an elite athlete. The owners Shane and Joe care deeply about the performance and knowledge they provide to all 8th Day members, and those looking to join.

— Alan

I've been running, doing triathlons and working out in gyms for about 10 years. This is the first time I have broken through plateaus and experienced real, noticeable results. These guys are great!

— Jason B

Fitness is often sought out yet seldom found. Most people concentrate so much on one aspect of training they miss out on becoming completely fit. At 8th Day Gym the workouts and programming are geared toward achieving total body fitness. Come in and find out how to increase your bench press by doing squats and become a faster marathoner by doing push ups and pull ups. Your results will be your reward.

— Eddie

I have been training at 8th Day for a year now. Never before have I experienced such gains in strength, agility, and stamina. 8th Day has not only become an incredible training facility for me, it is also my community. Everyone supports one another and cheers each other through some REALLY difficult workouts. Come find elite fitness training and the greatest community of athletes in Grand Rapids!

— Steve

What can I say!! This has been the best training I have gotten involved with! I have always been involved with sports and fitness, I did the triathlon thing, I was bored with workouts and group ex classes...doing the same ol' same ol'. I started at 8th Day this summer and love it. The workouts challenge the full body, have variety and are fun. The people are welcoming, friendly, encouraging and un-intimidating. The coaches are always willing to help and educate.
