Get Faster, Stronger, and Fitter with Arlington’s #1 Fitness Community

Arlington Sports Conditioning (ASC) has teamed-up with Team In Training (TNT) to help TNT athletes train for their events and meet their fundraising goals.

ASC is an athletic strength and conditioning program that has helped thousands of women and men burn fat, build lean muscle, and get faster, stronger, and fitter.

There are two ways that ASC can support TNT athletes:

Option 1- Discount code: ASC can give you a 25% off discount code for their public group workouts.

Option 2- Private fundraiser workout: ASC can host a private fundraiser workout for you and your friends. Minimum group size of 15 people.

With either option, ASC will donate 50% of your ticket sales to your fundraising page.

How to Get Started

Choose an option and email ASC Founder Pete Leibman (a TNT alum) at to get started.

How Is ASC Different?

Here are three ways that ASC is different from other group exercise programs:

1. ASC brings the gym outdoors: While most group exercise programs in Arlington are 100% indoors, ASC brings the gym outdoors. We train at the best outdoor locations in the area. We also bring a 100-decibel stereo and a van full of fitness equipment (dumbbells, slam balls, battle ropes, resistance bands, etc.) to our workouts. Working out outdoors provides much more space and variety, and it challenges you in ways that indoor workouts cannot. 

2. ASC eliminates tedious machines like treadmills, stationary bikes, and rowers: Most group exercise programs keep you stationary and make you spend a lot of time on tedious machines. Machines may help you burn calories, but they don’t improve your balance, coordination, agility, athleticism, or strength. ASC eliminates tedious machines and trains you with dynamic, athletic movements and functional equipment.

3. ASC is more effective AND more fun: ASC takes the good from other group exercise programs (accountability, expert guidance, great music) and removes the bad (crowded indoor spaces and tedious, ineffective workouts). Our program is more effective AND more fun.

How ASC Got Started

ASC started in 2012. At the time, ASC Founder Pete Leibman was teaching a weekly Sports Conditioning class for Gold’s Gym in Ballston. The class had become extremely popular, often getting over 100 people per class (photo below).

One summer day, Pete asked the group if they would be interested in doing a workout outdoors. Everyone was interested. Three days later, Pete hosted ASC’s first outdoor workout.

Over the next ten years, Pete led hundreds of outdoor workouts for thousands of people in and around Arlington.

More recently, ASC expanded its schedule to offer two different class formats and five workouts each week.

While most of our members have been with us for years, we are just getting started…
