Cardio Energie

I’m a 47 year old guy who has just started to go to the gym. Previously been reasonably fit (martial arts instructor and squash player) but have developed middle aged gut. I’m doing about 60 mins cardio (bike 2×20 and cross trainer 1 x 20), some powerplate (for abs and arms) and then doing chest and shoulder weights.

I want to lose my gut and build up my chest, shoulders and arms as I’ve always been conscious they are too puny.

I want to take the best mixture of supplements to support me. I used to take Cod Liver Oil and Glucosamine. I also tried some Hydroxycut which played havoc with my system.

So bearing in mind the workout I am doing three times per week, what do you think is the best supplement mix to be taking? I think Creatine will be a must but will happily take advice given.

I want something hopefully cardio wise that is under $200 so I can use it in my own home. I dont want weights im talking like leg machines, stationary bike, cheap yet effective treadmills. thanks.

Any effective cardio workout that can be done around the home without any fitness equipment, weights etc?
and also, someone told me jumping on the bed was a good form of cardio, is this true? and if so, any other fun things that can double as cardio?
