If you're into it that much, Daz, you might find it easier to do a three day 'push, pull, and legs' cycle, where you gym it everyday, but you'd spend less time than 80-90 mins at a go.
And another benefit of doing it like that is that you can maintain a high-intensity workout for a short period of time, but with longer workouts, towards the end, your intensity will decrease.
I only do three gym sessions a week; but I'm not after being a body builder; I use it to supplement my running.
im doing 3 full body workouts per week tosh(with at least a day off in between workouts) and happy with the results for sure but next week ill have to do 2 consecutive days due to family commitments/leeds festival next weekend so ill work upper body one day,legs the next.
my current routine is
20-30 mins warm up(stationary bike, yoga stretching and ab work)
an hour weight training with free weights dumbbells/barbells,cables,some machines.working all muscle groups.
im adding a bit of extra weight approx every 2 weeks as im getting used to training.
ive started mixing it up a bit each session(both high reps,lighter weight and low reps/heavier weights).
i find my intensity is fine as long as im not in the gym longer than 90 mins.plenty of carbs 2 hours before training and a cup of coffee half hour before gym.
no running for me but i walk the dog for 3 or 4 hours a week too.
Rather then concentrating on a total body workout on each workout, focus more on certain muscle groups.
My workout consists of
Sunday- total arm workout
Monday- total leg workout
Tuesday- biceps and back
Wednesday- abs and forearm's
Thursday- triceps and shoulders
Fri-sat- rest
I spend 45 mins max in the gym per session doing high intensity super sets. You don't need to do anymore then that or you can actually end up burning muscle.
Also you don't need much carbs, just the right amount to cover for your energy requirements, iv cut most of it out of my diet and concentrate on high quality proteins and nutrition instead. To much carbs can be a bad thing.
Optimum nutrition 100% gold standard whey is fantastic straight after a workout, especially mixed with pure coconut milk and a handful of spinach for iron.
Iv grown my 💪 by nearly 3 inches in 4 months, whilst reducing my body fat and leaning out at the same time.
For a job like ours it really does help being in good physical shape.
You can use any brush you like without crying about the weight for starters
