Another great post @deagonvegan, I love the Alternating DB Bench Press, i find any single arm / leg, press, pull or balance (one arm one leg ) plank to be hugely beneficial. I really think that a lot of people miss out on these exercises, they are great for core too I find.
Just out of interest how long in total do you limit your sessions to? I try not to spill over 1 hr 15 min excluding warmup and down and stretch. It can be 1 hr 40 min typically.
Thank you! Including a warm-up, I generally don't train for more than a hour.
