EASIEST WAY TO GET STRONG -
OKAY when I say easy I don't literally mean easy, shifting a ton of weight each week is by no means easy, you get what I mean. -
If you want to get strong, here's the winning formula:
Low variety of exercises. Don't use all these different exercises to "confuse your muscles". Stick with a few big compound exercises for each movement: squat, hinge, pull, and push.
Practice makes perfect. Want to get strong fast? Train the major muscle groups twice a week. See building strength as skill, the more practise you get the more neurological adaptations take place. Ever heard of any becoming excellent at something by training their skill once a week? -
Work up to a heavy set. If you feel like crap, stop here. If you feel good, keep going and work your way up to a max or PR. If you still feel awesome, do a few backoff sets.
Don't always try and hit PR's it can get too much for the CNS, listen to your body.
Rule of 10. I got this one from Dan John. Each workout should have approximately 10 total reps (not including warmups). So this could be as simple as 5 sets of 2, 2 sets of 5, 3 sets of 3, 5-3-2, or 6 sets of 1 (exception to the rule).
Progressive overload. At least once per week, try to beat your previous personal best. The goal is to get stronger, and the only way to do that is to attempt to hit PR's occasionally. If you're a beginner, you should try to hit PR's every workout. If you're an intermediate, you should try to add 5-10lbs to each big lift per month. If you're advanced, take gains when you can get 'em. It takes time and consistency. -
