Hi Brendan,
Firstly a huge thank you, as the advice and resources you're providing on here are invaluable. Amazing that you're doing it all free of charge and out of goodwill.

I've got two questions to ask if that's OK:

Firstly, I'm struggling to nail a balanced routine - I boxed when I was younger and did martial arts, but in recent years (I'm now 40), I've been purely fitness-focused and discovered crossfit about two years ago (training by myself rather than as part of a box). However, I took up MMA in August and I'm absolutely smitten - can't get enough of it. The biggest challenge, therefore, is that I'm finding it hard to fit everything in and need to get it more systematic. As things stand I've dropped the crossfit-style metcons recently on the basis that I'll be getting a similar workout from the MMA sessions anyway, and instead I've started following 'Starting Strength' on the basis that this will give me better balance in terms of my routine and get my base numbers higher - I currently weigh 75kg and my 1-rep maxes are around 130kg deadlift, 105kg squat and 65kg press. Only other issue I should mention is that the gym I'm using has an Olympic bar but no squat rack, so I'm currently alternating between front squats and overhead squats rather than doing back squats (as an aside, I'm finding that having to clean the bar to get into the front squat position is really taking it out of me as well - I'm currently doing 3x5 at 70kg).

At the moment I'm thinking of trying to do the following:

Sunday: MMA (wrestling) 6-7pm followed by Thai boxing 7-8pm
Monday: Starting Strength routine before work and then MMA (BJJ) 8.30-10pm
Tuesday: Rest Day
Wednesday Starting Strength before work then MMA (striking and sparring) 8.30pm-10pm
Thursday MMA (BJJ) 6-7pm; Thai boxing 7-8pm
Friday: Yoga 9am and BJJ technique work in the afternoon
Saturday: Starting Strength AM and then Wrestling 2-3.30pm

Would really appreciate your thoughts on that and what I should do to tweak/improve it.

The second question is that I've also realised I'd like to take my passion a stage further and achieve some professional qualifications in the fitness industry. The obvious one in the short-term seems to be the crossfit level one trainer course, but again, I'd welcome your views. Thanks and apologies for such a long one!
