The main aim of designing recumbent bikes is to enhance comfort and they, therefore, provide the desired comfort. They are made in a manner such that there is no pressure that is exerted on the neck or back or any other part of the body. The seat of the recumbent is made such that the back remains fully supported throughout the ride. The view of the entire place is on display and there is no straining of the neck as one struggles to view what is on their way. The wide surface area of the seat supports the weight exerted on the seat by the rider. The comfort experienced when riding a recumbent is therefore indisputable.
My female English Bulldog had her last heat cycle Nov. 2007. She had a healthy litter of puppies in January 2008. After delivery, we found out she had a small heartworm infection and underwent the IV treatment. It is now almost one year since her last heat cycle. Pups whelped in January, IV treatment in February..would that have "thrown off" her cycle? ALSO, let this be fair warning to all dog/cat owners..my female only missed two months of Heartgard in the summer of 2007..that is all it took for her to get an infestation...that was a very unfortunate, yet valuable (both financially and emotionally for us), lesson. DO WHATEVER IT TAKES TO REMEMBER TO ADMINISTER HEARTWORM PREVENTATIVE TO YOUR PETS!!
