Greasing the groove with chin ups going good since i installed a pull up bar a couple weeks ago.
In January I struggled to do 1 perfect chin/pull up with full rom. Now i can do 3 dead hang chin ups as my max when im fresh and it seems to be really blowing up my biceps and forearms.
Important to note im more overweight (fat) than i want to be, 5'10 male and 200lbs so I consider this huge progress.
Yesterday I done 22 reps of chins in total which is probably the most i ever done in a day. For the most part I was doing 2 consecutive reps per set but i think that's too close to failure for GTG training at the moment, my arms are sore today haha. Going to go back to 1 rep with rest in between and that should spare some fatigue and DOMS on my arms.
I would not consider sweat as a good marker for intensity, because I can certainly sweat while doing burpees but they do not creation enough tension to be considered a good strength training movement.
As Pavel Tsatsouline would say, do not confuse strength training with conditioning/endurance training. If the goal is to get as strong as possible then having a constantly elevated heart rate isnt necessary in the slightest as resting longer in between sets of lower reps (1-5) of relatively heavy lifts is better for strength training.
I prefer to keep them separate to get the maximum benefits of each. But you can also become a freak beast like Brian Alsruhe and do giant sets with everything (something like pullups to deadlifts to barbell rows to burpees, etc)
