well i dont think it's wise to jog 20min prior to any bodybuilding workout. if u say walk for 20min as a warm up then it's ok. if u insist in doing cardio, either do it after ur workout or have a separate cardio session, either later of the day or next day/rest day. dont spend all the energy on running when u can use that to build muscle by lifting heavier

if that someone is your PT, you should just fired him. Owh yea, if your current workout regimen of all machine is constructed by your PT, you should also fired him.

building muscles is far more superior way to lose fat rather than jogging. doing jogging and any other aerobic exercises albeit would burn fats then and there but it only burn until you're stop doing the exercises. there is no more burning fat happened after you've stopped and it only depends on your metabolism afterwards.

compared to building muscles, your metabolism will be higher (a lot higher than people who jog only). Higher metabolism will burn more fat while [B]RESTING{/B] and it will happened 24/7.
