You seem to be making a common mistake by dropping your weights and expecting the circuits to cut fat. There is no substitute for cardio and by dropping the weights you will lose the muscle you have (hopefully) built.
So advice, forget the gear, that won't get you out of trouble if you're training's wrong.
Keep the weights in, add cardio at least 3 x 30mins per week and cut the rubbish out of your diet.
Perhaps haven't explained propery mate but instead of my higher rep training which put on 10lbs in the last 3 months of last year and the pyramid training I reverted back to in jan which has put another 8lbs on I am simply training "slightly lighter"
i.e current 60x10,80x8, 100x8, 130x8 140kg x6, 155x2 bench press with 3 mins rest between would change to 60x10,80x8, 100x8, 130x8, 138x8, 120x10, 100-failure with a minute rest.
on other days I would superset this with lat pulls etc. so there isn't a lack of weight or a lack of reps, simply a different aproach to training to use up more calories in the gym
A mate of mine is a mma fighter and I did a few circuits late last year, and for those who say it in't cardio then I welcome them to try it, I got up to 180 on my heart rate monitor the first time and I only did a 20 minute session on 9 stations including kettle bell work.
Appreciate the advice regarding the diet, but thats never an issue when I cut only when I bulk as I find it difficult consuming so many "clean" cals lol!
Lowest bf I've been caliper tested at was 12% after a 5 week diet and cut mentioned previoulsy (was 32% beforehand) -- but I d drop muscle due to the fact I did gym 3 days a week, tabata training twice and steady cardio once hence trying to change it up this time
cheers fellas
