OP: this is a generational issue not limited to frum people. There are a million and one excuses not to exercise, one could even argue it is harder on young – frum – couples, with all the little kiddies running around, diets are also an issue, shabbos – b”h many simchas – makes it more challenging – harder access gyms, which may be a good thing. Gyms are hard pressed to make money, it is a very hard business model. Ask any gym, their cash cow is the member who signs up and is forced into 3 years but shows up twice and is stuck in a contract (30 a month, a gym would need 1500 – 2000 members to be able to pay rent in the heart of flatbush plus staff but the facility can’t handle that many people)- I would hope frum people are smart enough to avoid such contracts so yeah its a tough sell and a tough business so no surprises that it failed.
I would love to see a kosher version of P90X or the like anyone wanna film it with me? (i’ve done it im a fan)
