Scenic running tracks
Logan city has some great running tracks and outdoor fitness areas such as parks and ovals. A good one is Logan River Parklands located at Blackbird Street in Beenleigh, it has a scenic walking/running track and you can stop off and use the free exercise equipment along the way. If you are feeling more energetic and want to get your heart rate up even more, it also has a good flight of stairs just near the public restrooms which could be used for stair runs. Just next to the stairs is the park which also has various things such as benches you can use to do body weight exercises on such as dips, step ups and push ups to name a few.
Bring the dog
Located next to the park is a fenced in dog park so if you want to take your four legged friend for some exercise you can run around with him without bothering any of the other park goers. Just outside this area is a large grassy area you could use to do sprint exercises or perhaps some HIIT drills. You can do all of the above and more with a fantastic back drop and the sounds of nature while you are getting fitter and healthier.
