I noticed "standard" gymming like you see most guys do in the gym just didn't get rid of fat for me, when I switched over to unconventional training, example I bought 2x 40kg of concrete bags a while back, I train from Home in a 4 car garage so I have the space, I do a circuit up and down the garage carrying those 40kg bags and do as many reps possible in 2min, write it down on chalk board, then try and beat it next time, it's a killer I then follow that with Burpees Crossfit also a killer.
You'll feel muscles in your core you never knew you had, not only that but it makes you dead tired and hungry.
You can't out gym a ****ty diet
