Has anyone here used these products? If I would love to hear about your experience’s and thoughts on them.

Focus on 1 goal first ie lose fat or gain muscle, then get your diet in check for the goal you're focusing on ie. moderate deficit for fat loss or moderate surplus for muscle gain.

As for the supps listed Cellucor is ridiculously overpriced, if you wanted a fat burner and you already have your diet in check the only one really worth the money is EC. And the GNC multi is an over priced poorly put together multi

you don't need supplements to burn body fat. just a little more discipline, perhaps.

one thing...if you are not using a HRM to determine calories burned, chances are the machine estimate or MFP estimate are as much as twice as high as they should be. So, if you are eating back your exercise calories and using an estimate as a guide, chances are you are eating too much to lose weight. If this is the case, either get a HRM or eat back only half of the exercise calories.

second...drink 4-5 liters of water a day. try that for 2 weeks and see if it helps.

third...try to reduce the processed foods you are eating (if you are eating a lot of them). cook instead. you generally get something more fulfilling for your calorie buck that way...and much less sodium (assuming you skip the salt in cooking).

here's a rock solid, 25ish minute metabolic resistance routine (supersets involving non-competing muscles) that I recommend for burning fat:

do these supersets (a superset is 2 or more exercises without rest between the exercises...you rest from one superset to the next, but not for too long, 40-60 seconds of rest)

1. flat bench press + sumo squats with weight

2. incline bench press + deadlifts

3. assisted pull-ups + one legged bodyweight squats

4. flat chest flies + one arm rows

5. decline chest flies + jumping kickbacks (or leg curls)

6. shoulder press + jump squats (or regular squat with weight)

7. bicep curl + lying down tricep skull busters + lateral raise + front raise

8. tricep kickbacks (or dips) + stability ball leg curls + calf raises

9. medicine ball smashes + plank

** any of the exercises with weights can be done with dumbbells or barbell

I like to finish this routine off by going outside and running 4-6, 15-20 second sprints.
