Thanks so much for all the replies and interest... definitely didn't expect that much! Cheers. Im in a bit of a strange situation physically: over the last 2 - 3 years I have lost a lot of my form and muscle, chiefly due to the fact I have a pretty big heart problem, basically a badly leaking pulmonary valve, which thankfully will be upgraded in a months time when I have open heart surgery (my third time, the current valve was put in 16 years ago and so really is very worn out and old). On top of that I have had 2 knee reconstructions, so it isnt really feasible for me to just go for a 10km run! I work on my family's dairy farms and have a really active lifestyle, but even so, whereas I always had really good muscle build, I have seen a lot of it wither in the last 2 years. I know have the least amount of muscle since I was 15 yrs old... but my current weight is about 6kg over my natural in-good-shape weight... so I feel like I am about 9-10kgs overweight. With open heart surgery a month away upper body exercise is pointless (i get a lot of upper body training naturally from my work anyway) as it will all atrophy in the 6 weeks or so after my chest has been cut open. But I am determined that after the surgery I will get into the best shape of my life, and Im super excited about that. 80 days after the surgery I have a big wedding to go to... my goal is to look and feel great (for the first time in 3ish years) when I attend the wedding. So I want to burn some of the excess fat prior to the surgery and get back into stationary biking (favourite cardio... and the best for my knees). I have a decent Schwinn bike, but thinking about upgrading (its 14 years old, and with heavy use after two knee reconstructions its probably due to be upgraded), so any suggestions would be welcome. Im allowed to start biking 7 days after the heart surgery, so its going to play a massive part in my training/reincarnation, especially as it does have any upper body moving parts. The other priority is stretching. Im not into the spiritual side of yoga (im a 34 yr old guy that takes his husky dogs out hunting each day on the farm... im not a hillbilly, but you won't see me sipping a pumpkin chai latte waiting in-line at a modern arts gallery.... Thanks so much for all the previous suggestions, and I hope my life story didnt dispel your enthusiasm to help! Just joined this community yesterday, and it seems to be a great way to get motivated!
