Imageline, Inc. a clip art image licensing broker has threatened us with a very large lawsuit after finding a line drawing on ExRx.net.

The law firm representing Imageline, Inc. has offered to settle out of court for thousands of dollars if we are not able to produce our sales receipt and license agreement.

We missed Barack Obama when he worked out at Scott Fitness 3.0 in Kansas City, MO on Tuesday, Aug 26th. At this same facility, we have been shooting dozens of hours of exercise video to replace many of the aging exercise clips on ExRx.net. A staff member of Scott Fitness was contacted by the secret service that morning. Mr. Obama arrived at 8:30 AM along with dozens of federal agents. While agents stood guard around the building, Barack performed a leg workout consisting of heavy leg presses. While on the treadmill, he appeared to be reading in the dimly lit room. Approximately 40 minutes later, he left with his entourage. Interestingly, no other club members were using the facility at the time of his workout. This location is the newest and least utilized of the Scott Fitness KC metro chain. In a large warehouse/workshop building located in the crossroads, this facility is uniquely styled with 1950 to 1970 decor. In addition to an art gallery, an old living room, dining room, kitchen, and a restaurant setting with vintage paraphernalia surround the exercise areas - kind of like working out at a museum, or great grandma's house!

ExRx.net average data transfer has exceeded one Gigabyte daily.
7 Feb 2002
We have tried 5 hosts in the last 8 months. Someone finally recommended web host Glorb Internet Service. They have the best service of any web host we have ever encountered; outstanding customer service!
1 Feb 2002
ExRx was cited a number of times in a Fitness Management (Feb 2002) article "Pre-Participate Health and Fitness Assessment" (pgs 44-49) as a resource for online fitness testing calculators and procedures.
29 Jan 2002
We began receiving notices from our current host that ExRx.net is exceeding its bandwidth quota despite the company's advertisement for unlimited bandwidth. It is time to look for a new host, particularly since we have been receiving terrible customer service. Also, visitors have reported difficulty in loading pages during peak hours. "Your site exrx.net has exceeded its bandwidth quota in the period beginning on 2002-01-08. Your quota is set to 15728640000 bytes, and your site has consumed 785801826 bytes beyond that quota."
8 Jan 2002
We found another new host since our last web host pulled the plug due to our high traffic. Incidentally, as the other hosts, they advertised unlimited bandwidth.
12-17 December 2001
Our host took ExRx.net down despite us believing we had come to an understanding. Desperately searching for a new host! ExRx.net is only 22 MB and hosts 3,000 to 5,000 individual visitors daily.
16-18 Nov 2001
I had the honor in attending the 3rd Annual SWIS Symposium. speakers included Bill Pearl (history of weight training) Dorian Yates (Mr. Olympia) and Bill Kazmaire (world's strongest man), and Ian King (strength and conditioning guru), Dr. Digby Sale, PhD (neural adaptation to strength training), Dr Mauro di Pasquale, MD (world's foremost expert on drugs in sports), and of course, Dr. Eric Serrano, MD (Cutting Edge Supplements). I also had the privilege to meet Mohamed Makkawy, Scott Mendelson, and Mistress Krista.
26 Oct 2001
Dr. Ken Kinakins of SWIS visited ExRx.net and invited me to Toronto, Canada as his guest to attend the International Weight Training Injury Symposium which he hosts. He noticed I knew Dr. Eric Serrano, MD, my old classmate, roommate, and ExRx.net benefactor. Eric will be one of many presenters at this conference.
2 Nov 2001
Although our host promised unlimited bandwidth they have threatened to take ExRx.net down because it generates 17 Gigabytes of traffic monthly, although we only have about 4000 individual visitors daily. ExRx has had this much traffic since we started our account with them in June. Just last Thursday, though, a representative called me and said we have exceeded the 5 GB monthly bandwidth capacity and we may be taken off line as soon as that evening if we don't pay more. They are trying to extort us to pay 5 times as we pay now; we've already paid up until June 2002 and if we go somewhere else they will charge a penalty fee to buy back my domain name, although it is in my name.
6 Sept 2001
In the past, we were able to answer an occasional exercise related question. We'd continued to receive such an overwhelming number of e-mails seeking advice, we were unable to answer the numerous inquires. As a result, we are proud to announce ExRx Consultation Service for those earnestly seeking our personal and professional assistance. We appreciate your understanding and patronage. Sorry, we have discontinued this service. Please post your questions on our Forum.
