A friend of mine asked advice on building a home gym that is compact and affordable.
Here was my answer: real iron dumbells 2×10, 2×20 and if budget permits 2×30. A suspension trainer. Keep it simple. Start with that. You can do plenty with this basic setup that takes no space. As interest grows, you can invest every year.
I started investing and building my home gym two decades ago and I am pretty happy with the results.
