Is this a decent workout routine?

[frogstomp]

Hey all, been lurking this forum for a while and wanted to get your opinion of the TNT workout on Mens Health. I'm 23 and started going to the gym again 2 months ago after a long layoff due to injuries (acl tear), poker and laziness. Basically just want to get in decent shape ( for me, like most, that means add some muscle and lose the gut). I was really struggling at the start but am encouraged by the progress i've made recently but my gym sessions are all over the place and i dont really have a set routine. The TNT workout seems pretty straight forward and I am familiar with all the exercises. I plan on lifting 3 times a week and cardio ( spinning classes at my gym) 2-3 times a week. Any advice bros?
