Well, after spending money on gym fees and not attending as often as I should, I've made the wild decision to buy a home gym. A Revolution HG636S will be delivered and installed in my garage by some beefy folks. My wife and I will be able to use this machine as often as we can without drama. 

We're not looking to add huge muscle mass, just trying to outweigh (pun intended) the loss of same as we get more mature. Well, she is. Not me. This video shows two extra features added; ours will be as per the photograph.  See their site: https://revolutionfitness.net.au/product/revolution-636-home-gym/
