"Re; the comment regarding needing more weights and less cardio machines, I always think free weights are easy to do at home, but not everyone has space or money for a cardio machine (i wish)"

I'd say the opposite. Cardio doesn't need a machine in a gym - you can run outside, cycle, climb stairs, go for a long walk, do some body-weight circuits with burpees - or use minimal equipment like skipping with a rope or kettlebell swings etc. And many people don't use machines in the gym to get most benefit (e.g. putting the incline on the treadmill up and then hanging onto the bar for dear life).

Free weights are easy to do at home if you're primarily using hand weights for arms/shoulders or as a beginner to squats/deadlifts.chest press. As soon as you want to progress though, you're talking about some really expensive weights, benches and cages - which all take up far more room and cost more than the average exercise bike.
