I finally got around to joining our local gym and went for the first time this week. I have gained around 3 stone in a couple of years, and I was already overweight so I have been really feeling it in my energy, breathlessness, sleeping etc. Hence joining the gym. I went this week and OMG, I really struggled! I just did the bike and cross trainer, 10 minutes on each, to test my fitness levels and I was puffed out. I had a headache for the rest of the day. I am going again tomorrow and will do the same workout so I can see the improvement but please someone tell me it gets better!
