Toivo,
The outdoor circuit training....as you describe....can be loads of fun and very invigorating. It's something I'd wholeheartedly endorse.
I set up a course a few years ago with a friend of mine who, by the way, is 12 years older than I am. And I'm well.....not young...
It went like this....
- 1min jump rope
- 1min rebounder
- 1min crunches on stability ball
- run around the house several times and navigate obstacles. There were numerous ropes tied between two trees. Some we had to jump over. Some we crawled under. One person lead and the other followed. We also included side-to-side running, backwards running, one-legged hops, two-legged hops, bounding, backwards running and whatever else we could think of. Then we ran down to the basement.
- pull-ups
- 1min shuttle run
- Back outside where we played a hole of wiffle ball golf....and/or threw a football around....and/or kicked a soccer ball around etc.....
Repeat 2 more times for a total of 3 circuits.
It was a lot of fun and we got really strong and ran quite well. I ran 38:55 at Falmouth which was a good result for me. It was a little tough to sustain because I didn't have the time to keep inventing new circuits. But the idea was good and I've gone back to it on numerous occasions.
I think the reason we succeeded with it was that we didn't make it too hard and we had developed a bit of strength before jumping in to it. And we added "stations" that were fun and slightly silly. We didn't necessarily care if it had any other purpose except to keep moving and have fun.
So...there you go....we looked like idiots but what the hell.
I think that your instinct to play more is a good one.
