Our sales and marketing team was already utilizing Sales Force as their CRM platform, so we searched for a solution that would plug into SF, or better yet would run on SF. The software we looked at that ran outside of the SF platform required a connector software to push and pull the data in and out of SF.
Push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole.
The major muscle groups used for chin-ups are the latissimus dorsi back muscles and biceps brachii arm muscles, but other back, arm and shoulder muscles assist the lats. Compared to pullups, chin-ups use the pectoral muscles more at the start of the movement and focus the biceps and forearms slightly more.
