I just don't feel anything in my back activating while my arms get tired as fuck. Yes,i can do 3x5 but still. I did try out the \"drive\" elbow into the ground method but doesn't seem to do much. Maybe my back muscles are so weak my arms pick up the slack? I do sit a lot in front of the 'puter every day which may have resulted in a weak back however i also played football every week for several years.","topicHash":"8e0916fc91745818129463af6763b19b095a396fa9b9a911ca3d4d899d13d0b2","topicName":"fitness","parentHash":"a496223f53f2bc88776985dba527ada615c99934374c4e7c61198149f192b554","costSunk":"0","biasSupport":0,"biasOppose":0,"biasVouch":0,"biasNull":0,"blockHeight":null,"confirmations":0,"timestamp":"2026-10-24T17:05:09.450Z","tripFp":"9ab9a084cd4c","viewCount":0,"powDifficulty":0,"relation":0,"ephemeral":true,"nonce":"3bf0ca3d317a0e66","sig":"015406b29307efbe9228c628f342f5422bfc17da759129aea93728fa5c0ee0cd2cc2cef46929f774eb55821671fd12689675adf5e703dea778d7272c3cf3f9e0","ephStamp":{"blockHashHex":"00000000000000000000dc055c47398972cbc9523c99b6dbde07ddf8a0e3adde","nonceHex":"f27b010000000000"},"replyCount":0,"chainReplyCount":0,"vaporReplyCount":0,"clusterSize":1,"receiptHeight":972950,"expiryHeight":977270,"authorMarks":{"since":"2026-10-24T16:04:22.377Z","via":"sight","inscribed":0,"likes":0,"biases":0},"lang":"en"}],"nextCursor":null,"pageReceipt":{"host":"6af58b1822e0cabfe57d76540f745d059b438f489a796ec6a705c6540233845e","t":"2026-11-08T20:30:57.715Z","sig":"c0df7df1c43ed312e3f3012d33e4d7379f59441a084a157c97fb84debfc7008534776c2d1c77306e2e9a8cfea8f5348c7c9d4a139b7d9d57d0a6902bb496470b"},"marks":{"since":"2026-10-24T16:04:22.377Z","via":"sight","inscribed":0,"likes":0,"biases":0}}
