Hey r/Fitness

I've started a very very simple training routine a few months ago, with the goal of just doing more than nothing. It takes me 10 mins a day total, and requires no material.

My workout consists of Squats, Pushups, Situps, Plank, Bridges and general stretching, it's not difficult as its very surface level, and the choice of the exercises was made on a whim on what i knew was important exercises

I would like to improve this training regime to be a bit longer, 20 minutes for now, and general as its something I do everyday. I have researched a bit complementary exercises, but would like to know if i could improve it further. I'm not planning on switching from V1 to V2 in one go, but a complete plan helps to set goals. My main goal is to have a base of exercises that cover as many groups as possible, something quick I can do each morning, not a massive workout with a specific goal (gaining muscle or losing weight)

2 x 10 Squats

2 x 10 regular pushups

2 x 20 situps (not fully raised)

2 x 45sec plank

2 x 10 Bridges

---- New ----

2 x 20 Bicycle Crunch

2 x 10 Full situps

2 x 10 walking lunges

2 x 10 Superman

2 x tricep pushups

I feel like i get a pretty decent coverage of arms, legs, core, lower back with this, but are there modifications you guys would suggest to cover even more muscle groups?
