I just thought I'd share with you my workout from yesterday whilst I was using the gamma labs pre workout sachet. If you want to give this a go then please feel free, I'm only sharing It because of how I feel today (in pain) so hopefully you can use it and get some decent results. My glutes, quads, calves, upper and lower abs have pretty much all been effected by this, no hamstring soreness though so I'd advise throwing in an extra set isolating hamstrings, maybe just the machine curl will do.
Let me know what you think.
