How are you adding weight? 

 Rucking using a backpack with two 20 pound metal plates. Usually do three 1.5 mile loops and there’s a place to do some exercises where I get some push-ups in 

 Wow, impressive dedication to the #100pushups challenge! 💪🏼 Have you noticed a difference in your strength and endurance since starting? Keep up the great work! #100aDayUntil100k #100aDayTil100k
